There are 3 possibilities. 1 the coil. 2 the ignition module. 3 the pick up coil. In my experience the ignition module is the most common cause. It is in the distributor held in with 2 screws. The coil and module can be tested at any parts house. Good Luck

I changed my coil packs, the car run fine. I sbut it off and went to restart the car, it turns over, is getting gas, and is not getting spark. What is the cause? And where is the crankshaft position...


retrace your steps, what didn't you do ? take your time, review your work, clear any trouble codes from your computer , are your connections good ? check each spark plug to see if your getting spark. if not,then the entire distributor assymbly may need replaced, check cap & rotor, are spark plugs good? if no spark, then no voltage is getting to plugs from distributor assembly, (power transistor, ignition coil, or camshaft position sensor.) is ignition switch recieving battery voltage ? is ECM recieving bat. voltage ? make sure all fuses are OK .every time you do something. dry out any moisture in dis cap/rotor. check ECMrelay, the goal here is to get SPARK to spark plugs, remember that ! keep it simple, one step @ a time. ( do you have a haynes repair manuel, they cover this problem, that way you can test these things as they present them. GET ONE ,NOW!

You have not run a OBD2 electronic engione control fault code test, get a code reader and do that first and don't replace anymore parts until that is done and you have the fault codes and have done the proper diagnostics for each code.

1985 dodge w350 with 360 ci engine,no spark, replaced coil, cap ,rotor, pickup unit ,ignition module,could it be ignition switch? acts like it wants to fire when i wiggle ignition with key


could be if the engine is not getting voltage from the ignition switch. take a test light and check for battery voltage at the coil and module when you turn the switch on.

check with an oscilloscope if the signal comming out of the ECM to the ignition coils is OK. You can see that way if the problem comes from the ECM or not.

My engine turns but no spark I changed ignition coil and still no spark,what could it be?


Depending on which engine your car is equipped with; the following components could be at fault.

Crankshaft Position Sensor
Camshaft Position Sensor
ECM (Engine Control Module)
Distributor Cap or Rotor
Fouled Spark Plugs
Bad Plug Wires

If they haven't been replaced in the last 30K miles, I suggest you check and /or replace the the plugs and wires first.

If your engine is equipped with a distributor, check and/or replace the distributor cap and rotor if it hasn't been replaced in the last 30k miles.

If your engine is equipped with crank or cam sensors have them tested.

1989 GMC engine turns great , no spark at coil or plugs, had coil tested and repalced- new rotor and cap. not sure where to go next


Check your fuses (ECM) and also recheck your wire leads to the coil. Your ICM (ignition control Module) may also be bad, it's located in your distributor under the rotor. You can have that tested also to make sure it's working 100%, there common to go bad from corrosion caused by condensation under the distributor cap.
Thank you for using Fixya and good luck.

My 88 olds cutlass supreme FWD will not start. I have replaced the ignition module and ecm computer. I am getting fuel but no spark. The engine turns over fine.It just won't start. where do I go next?


If the engine won't start, perform a spark test as described earlier. This will narrow the problem area down considerably. If no spark occurs, check for the presence of normal battery voltage at the battery terminal (BAT) 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 at 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.
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 a ohmmeter between the TACH and BAT terminals in the distributor cap. The primary coil resistance should be less than 1 ohms.
  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.

I had the same problem recently but replacing the ignition Coil under the distributor (inside) solved the problem. Also replaced the distributor Cap and rotor at the same time.

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
