What would cause a no spark condition besides the coil,pick-up controlmodule and coil, ignition switch, battery, and associated wiring?

Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

If theres no spark from the spark plugs then you would have to replace them?

A bad wire on starter. Bad hot wire to distributor. Both could cause no spark. Check for power at distributor. If that's good check for bad wires at starter. Those are first to check. Will check in for what you got in a bit. Hope this helps ya

Well, you know the ignition coil has to be good. then the ignition control module inside the distributor has to be good. It controls the ignition coil firing times. This module can be tested at a parts store. And then, also in the distributor and attached to the ICM is the pick-up coil which tells the computer crankshaft position, so the computer knows when to signal the Ignition Control Module that it is to cause spark out of the coil. These are the components of the ignition system, so you know how to check them. Ignition coil, ICM, pick-up coil, and the pcm, computer.

First, check that power is getting to the coil when the key is turned to on. The coil must have battery voltage applied to it before it can cause spark. If there is power there, test the ignition coil, test the ICM, then the pick-up coil. If your wiring is good, one of them components may have failed. And of course, the last thing to suspect is the computer, the pcm. Hope you don't have to get that far.

It has everything to do with the firing. Ignition system consists of the computer, the crank and cam position sensors, the coils, spark plugs, ignition control module, the ignition switch, and the associated wiring.

If you have no fire (no spark), one would start by checking if ignition switch turning on causes the coil to receive battery voltage on the coil primary wire.
Always check for trouble codes when an engine problem develops. Codes stored in memory may have clues to why it won't start. If no codes are present and no spark (no ignition), suspect a bad crank position sensor (it can be tested by a shop), or possibly a bad ignition control module (also can be tested at a parts store for free).

1. Connect an ohmmeter between the TACH and BAT terminals in the distributor cap. The primary coil resistance should be 0 or nearly 0 ohms . If not replace the coil.
2. To check the coil secondary resistance, connect an ohmmeter between the rotor button and the BAT terminal. Note the reading. Connect the ohmmeter between the rotor button and the TACH terminal. Note the reading. The resistance in both cases should be between 6,000 and 30,000 ohms. Be sure to test between the rotor button and both the BAT and TACH terminals.
3. Replace the coil only if the readings in Step 1 and Step 2 are infinite resistance or out of specification.

All tests included below.

The symptoms of a defective component within the HEI system are exactly the same as those you would encounter in a conventional system. Some of these symptoms are:


Hard or No Starting Rough Idle Poor Fuel Economy Engine misses under load or while accelerating.
If you suspect a problem in your ignition system, there are certain preliminary checks which you should carry out before you begin to check the electronic portions of the system. First, it is extremely important to make sure the vehicle battery is in a good state of charge. A defective or poorly charged battery will cause the various components of the ignition system to read incorrectly when they are being tested. Second, make sure all wiring connections are clean and tight, not only at the battery, but also at the distributor cap, ignition coil, and at the electronic control module.
Instruments designed specifically for testing HEI systems are available from several tool manufacturers. Some of these will even test the module itself. However, the tests given in this section will require only an ohmmeter and a voltmeter.

CAUTION The HEI ignition system can generate voltage of 30,000-50,000 volts. When testing the system, DO NOT hold a spark plug wire while the engine is running or cranking. Personal injury and or damage to the ignition system may result if this caution is not followed.
Since the only change between electronic and conventional ignition systems is in the distributor component area, it is imperative to check the secondary ignition circuit first. If the secondary circuit checks out properly, then the engine condition is probably not the fault of the ignition system.
If the engine won't start, perform this test. This will narrow the problem area down considerably.

1. Remove one of the plug wires and insert a HEI spark tester tool in the plug socket.
2. Ground the spark tester to the block and crank the engine. DO NOT touch the spark plug wire while the engine is cranking.
3. The spark should be crisp and bright blue in color. If a normal spark occurs, try each spark plug wire until a no spark condition or a weak orange color spark is found. If all sparks are good, the problem is probably not in the ignition system. Check for fuel system problems, or fouled spark plugs.

If no spark occurs, check for the presence of normal battery voltage at the battery (BAT) terminal in the distributor cap. The ignition switch must be in the ON position for this test. Either a voltmeter or a test light may be used for this test. Connect the test light wire to ground and the probe end to the BAT terminal at the distributor. If the light comes on, you have voltage to the distributor. If the light fails to come on, this indicates an open circuit in the ignition primary wiring leading to the distributor. In this case, you will have to check wiring continuity back to the ignition switch using a test light. If there is battery voltage at the BAT terminal, but no spark at the plugs, then the problem lies within the distributor assembly. Go on to the distributor components test section.


If the engine runs, but runs roughly or cuts out, make sure the plug wires are in good shape first. There should be no obvious cracks or breaks. You can check the plug wires with an ohmmeter, but do not pierce the wires with a probe.
If the plug wires are OK, remove the cap assembly and check for moisture, cracks, chips, carbon tracks, or any other high voltage leaks or failures. Replace the cap if any defects are found. Make sure the timer wheel rotates when the engine is cranked. If everything is all right so far, go on to the distributor components test section.
DISTRIBUTOR COMPONENTS TESTINGSee Figures 2 and 3
If the trouble has been narrowed down to the units within the distributor, the following tests can help pinpoint the defective component. An ohmmeter with both high and low ranges should be used. These tests are made with the cap assembly removed and the battery wire disconnected. If a tachometer is connected to the TACH terminal, disconnect it before making these tests.

1. Connect an ohmmeter between the TACH and BAT terminals in the distributor cap. The primary coil resistance should be 0&omega or nearly 0&omega . If not replace the coil.
2. To check the coil secondary resistance, connect an ohmmeter between the rotor button and the BAT terminal. Note the reading. Connect the ohmmeter between the rotor button and the TACH terminal. Note the reading. The resistance in both cases should be between 6,000 and 30,000&omega. Be sure to test between the rotor button and both the BAT and TACH terminals.
3. Replace the coil only if the readings in Step 1 and Step 2 are infinite resistance or out of specification.

Fig. Fig. 2: Checking coil resistance. Ohmmeter 1 shows primary test. Ohmmeter 2 shows secondary test.
These resistance checks will not disclose shorted coil windings. This condition can only be detected with scope analysis or a suitably designed coil tester. If these instruments are unavailable, replace the coil with a known good coil as a final coil test.

1. To test the pick-up coil, first disconnect the white and green module leads. Set the ohmmeter on the high scale and connect it between a ground and either the white or green lead. Any resistance measurement less than infinite requires replacement of the pick-up coil.
2. Pick-up coil continuity is tested by connecting the ohmmeter (on low range) between the white and green leads. Normal resistance is between 650 and 850&omega, or 500 and 1,500&omega on 1977 and later models. Move the vacuum advance arm while performing this test (early models). This will detect any break in coil continuity. Such a condition can cause intermittent misfiring. Replace the pick-up coil if the reading is outside the specified limits.
3. If no defects have been found at this time, and you still have a problem, then the module will have to be checked. If you do not have access to a module tester, the only possible alternative is a substitution test. If the module fails the substitution test, replace it.

Fig. Fig. 3: Pick-up coil testing

Start by testing the ignition coil primary, and secondary resistance.

To measure the primary resistance, connect an ohmmeter between the positive (+) and negative (-) terminals (the terminals which are connected to the engine wiring harness) on the coil. To test the secondary resistance, connect an ohmmeter between the positive (+) coil terminal and the high voltage cable terminal on the coil. Then, measure the resistance between the positive (+) coil terminal and the coil case; the resistance for the case should exhibit infinite resistance. For coils manufactured by Diamond, the primary resistance at 70-80°F (21-27°C) should be 0.97-1.18 ohms and the secondary resistance should be 11,300-15,300 ohms. Coils built by the Toyodenso company should exhibit a primary resistance at 70-80°F (21-27°C) of 0.95-1.20 ohms and a secondary resistance of 11,300-13,300 ohms. Replace any coil with a new one if it does not meet the specifications.

FAILURE-TO-START TEST Before proceeding with this test make certain that spark has been checked for at the coil. Refer to the ignition coil testing procedures. Failure to do this may lead to unnecessary diagnostic time and wrong test results. CAUTION
Be sure to apply the parking brake and block the wheels before performing any test with the engine running.

1. Check the battery voltage. It must be at least 12.4 volts to perform the test. If the battery voltage is not at least 12.4 volts, refer to Section 1 for battery charging procedures.
2. Crank the engine for 5 seconds while monitoring the voltage at the coil positive (+) terminal. If the voltage remains near zero during the entire period of cranking, refer to Section 4 for the On-board Diagnostic checks. The checks will test the PCM and the auto shutdown relay.
3. If the voltage is at near-battery voltage and drops to zero after 1-2 seconds of cranking, refer to Section 4 On-board Diagnostic procedures. The problem is likely to be related to the distributor reference pick-up circuit to the PCM.
4. If the voltage remains at near battery voltage during the entire 5 seconds, with the key OFF, remove the PCM 60-way connector. Check the 60-way connector for any terminals that are pushed out or loose.
5. Remove the connector to the coil positive (+) and connect a jumper wire between the battery positive (+) terminal and the coil (+) terminal.
6. Using the special jumper wire shown in the illustration, momentarily ground terminal No. 19 of the 60-way connector. A spark should be generated when the ground is removed.
7. If a spark is generated, replace the PCM with a new one.
8. If no spark is generated, use the special jumper wire to ground the coil negative (-) terminal directly.
9. If a spark is produced, inspect the wiring harness for an open circuit condition.
10. If no spark is produced, replace the ignition coil with a new one.

TESTING

1. Check for stored trouble codes, then proceed as follows:
   • Fault code 11 - proceed to the next step.
   • Fault code 54 - proceed to step 6.
   NOTE: Before proceeding, verify that a minimum of 12.4 volts is available from the battery for operation of cranking and ignition systems.
   
2. Test the distributor pick-up signal reference circuit as follows:
   1. Turn the ignition switch to the OFF position.
   2. Unplug the distributor pick-up connector.
   3. Remove the coil wire from the distributor cap and have an assistant hold it 1⁄4 in. (6mm) from a good engine ground.
   4. Turn the ignition switch to the ON position.
   5. Connect a jumper wire to the gray (GY) wire terminal and touch the other end of the jumper wire to the black/light blue (BK/LB) wire terminal on the distributor harness connector several times. While performing this, observe the coil wire.
      • If there is spark from the coil wire, proceed to the next step
      • If there is no spark from the coil wire, the problem is in the engine controller or wiring.
3. Check the power supply to the distributor reference pick-up as follows:
   1. Turn the ignition switch to the ON position.
   2. Connect a voltmeter between the orange wire in the harness connector and a known good ground.
      • If the reading on the voltmeter is 8-9.5 volts, proceed to the next step.
      • If the reading is anything but 8-9.5 volts, check for problems in the circuit between the reference connector and the engine controller.
4. Check the mechanical operation of the distributor as follows:
   1. Turn the ignition switch to the OFF position.
   2. Remove the distributor cap from the distributor housing.
   3. Crank the engine while observing the ignition rotor.
      • If the distributor rotor revolves while the engine is being cranked over, replace the distributor pick-up coil assembly with a new one.
      • If the distributor rotor did not rotate, inspect the engine for a mechanical fault and repair as necessary.
5. If fault code 54 (No distributor sync pick-up signal) is being received, or was received before performing this test, proceed as follows:
   1. Turn the ignition switch to the OFF position.
   2. Unplug the distributor pick-up connector.
   3. Connect a voltmeter to the tan/yellow (TN/YL) wire of the harness connector.
   4. Turn the ignition switch to the ON position.
      • If the reading on the voltmeter is at 4 volts, replace the distributor pick-up coil assembly.
      • If the reading is 0 volts, check for an open in the wiring harness between the reference connector and the engine controller.

fuses, relay, corrosion at wire connections, ignition switch, pick up coil, ignition control module. Is the distributor rotor turning when you crank the engine? I ask this because a broken timing belt would cause a no start condition.

The first thing is do you know when the last time was that the distributor cap, ignition rotor, and spark plug wires were changed?

There is the possibility that the ignition coil is faulty and first check to see if full battery voltage is getting to the "Pos" (+) positive side of the ignition coil when the key is in the "Run" position, and also that full battery voltage is getting through the "Pos" (+) or positive side of the ignition coil and over to the distributor ignition module, dis-connect the wire connector from the ignition module and if battery voltage is not present at the connector to the ignition module with the key in the "Run" position but it is present at the "Pos" side of the ignition coil, then the ignition coil is faulty. If battery voltage is present then check the ohms between the high tension terminal (where the coil wire goes on the ignition coil) and the "Pos" terminal on the ignition coil by first dis-connecting the wires from the ignition coil and then test with the "Neg" lead from the ohm meter in the high tension terminal on the ignition coil, and the "Pos" lead from the ohm meter to the the "Pos" terminal on the ignition coil, and the ohm reading should be between 6,000 and 30,000 ohms and if not replace the ignition coil. A faulty ignition coil can also damage the ignition module.

The ignition module and the pick-up coil/stator located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil, and a faulty ignition module can cause any one of these systems to malfunction.

That could be a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores. If the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

Let me know if you require a firing order diagram any further assistance with testing or diagnostic procedures.
