No start no fuel or spark


What about your ignition module? I can't tell if you just replaced coils or ignition module included? Also, before buying anything, check voltage and ground for ignition module. Pink wire is voltage, black wire is ground.

The crank sensor sends ac signal to ignition module, the module converts signal to dc, something the computer can handle, then sends rpm signal to computer.

Coil quit firing


If you have no spark from two of the four towers of your coil pack, you need to check the wiring between the coil pack and the ignition module. Since you have spark at two towers, that proves you have power to the coil pack. Both sets of coil windings in the coil pack are fed by the same B+ feed,(red and light green wires to both coil packs too). The control side wires from the ignition module to the coil packs are tan/light green and tan/light blue for one coil pack.-----------------------------------------------------------------------------------------

1999 chev blazer won't start new fuel pump


So, do you hear the pump buzz on, when key is on? If that's good, then check your ignition circuit: check for spark at a plug. Use insulated pliers, hold end of plug wire 1/4 inch form engine bolt or ground source. When cranked, you should see a bright blue spark. Yes? Try another plug wire, too. No? Try another plug wire. If you have NO spark, could be your coil, coil pack, crank position sensor, ignition module. I would recommend using a diagnostic flow-chart to go through the ignition circuit. That way, you are not replacing unecessary parts_Expensive! Of course, if you have spark at plugs, your ignition circuit is good! Then you have to look further, like your injector circuit. Good luck.

I'm only getting spark out of one of the coil packs and the car turns over put won't start, please help me. Thank you


Try switching the ignition coil with the other coil and plug it in and check for spark again. If it works in the other coil location, then you need an ignition coil. Your engine is bad for valve cover gasket leaks which deteriorate the spark plug wires, so if you are going to put in plugs and wires with the new coil, I would recommend replacing the valve cover gasket and spark plug tube seals(included with the valve cover gasket set).

It will start then die if i hold the gas peddal down it will run for a min but it sputters really bad and backfires it has a new crankshaft sen dont know were to go next all this just started one day


sounds like your ignititon control module is going bad,this controls you spark and timing by a electronic brain.. THe location of your ignition control module is underneath the spark coil packs. if you follow your spark plug wires from your spark plug backward to the coil packs. if it is a 6 cylinder you will see 3 black coil packs with 2 wires attached to each coil. the coils are held in place by a few screw each,just make sure you mark each coil with tape so you do not get them mixed up when you take them off, I dont know what year your vehicle is but if it is more them 10-12 yrs old and has never been replaced,then i would replace it .I know because i have experienced these same kinds of problems with my general motor vehicles i have owned..

My 2003 honda accord v6 refuses to start. It cranks but no spark on the plug. What should i do?


Either the spark plug is faulty or the coil pack is faulty.The spark plugs get power to spark from coil packs.

If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).

But if the coil has voltage, then problem may be a bad high voltage output wire from the coil to spark plugs or hairline cracks in the coil output tower.------Getting this all possibilities checked will point towards the exact faulty part which is to be replaced.----------This should help.Thanks.Helpmech.

Hey there,i have a 1991 msuatng LX with the 2.3L ho engine running an 8 plug head. it sounds like i may have a misfire of some sort or my timing may be out but im not sure how to tell, could someone give...


Insert each wire on the proper terminal of the ignition coil. Ensure that the coil boots are fully seated and both locking tabs are engaged. The terminals are identified on the ignition coils. Install wires as shown in the illustration. The 2.3L firing order is 1-3-4-2 for both ignition coil assemblies.

Distributorless Ignition System In the distributorless ignition system (DIS), all engine timing and spark distribution is handled electronically with no moving parts. This system has fewer parts that require replacement and provides a more accurately timed spark. During basic operation, the EEC-IV determines the ignition timing required by the engine and a DIS module determines which ignition coil to fire.

Components
The distributorless ignition system (DIS) for the 2.3L twin spark plug engine consists of the following components:
  • Crankshaft timing sensor
  • DIS module
  • Two ignition coil packs
  • Spark angle portion of EEC-IV
Crankshaft Timing Sensor
The crankshaft timing sensor is a dual hall effect magnetic switch, which is actuated by the dual vane cup on the crankshaft pulley hub assembly. This sensor generates two separate signals, PIP (profile ignition pick-up) and CID (cylinder identification). The PIP signal provides base timing and RPM information, while the CID signal is used to synchronize the ignition coils. Initial timing (base timing) is set at 10 degrees BTDC and is not adjustable. Ignition Coil Packs
Two ignition coil packs are used for the 2.3L dual plug engine. The two ignition coil packs are triggered by the DIS module and are timed by the EEC-IV. Each coil pack contains two separate ignition coils for a total of four ignition coils. Each ignition coil fires two spark plugs simultaneously, one spark plug on the compression stroke and one on the exhaust stroke. The spark plug fired on the exhaust stroke uses very little of the ignition coils, stored energy, and the majority of the ignition coils, energy is used by the spark plug on the compression stroke. Since these two spark plugs are connected in series, the firing voltage of one spark plug will be negative with respect to ground, while the other will be positive with respect to ground. Refer to thePowertrain Control/Emissions Diagnosis Manual for additional information on spark plug polarity. DIS Module
The main function of the DIS module is to switch between ignition coils and trigger the coils to spark. The DIS ignition module receives the PIP and CID signals from the crankshaft timing sensor, and the SPOUT (spark out) signal from the EEC-IV module. During normal operation, PIP is passed on to the EEC-IV module and provides base timing and RPM information. The CID signal provides the DIS ignition module with the information required to switch between the coils for cylinders 1 and 4 and the coils for cylinders 2 and 3. The SPOUT signal (from the EEC-IV) contains the optimum spark timing and dwell time information. The dwell time is controlled or varied by varying the duty cycle (duration) of the SPOUT signal. This feature is called CCD (computer controlled dwell). Therefore, with the proper inputs of PIP, CID and SPOUT the DIS ignition module turns the ignition coils on and off in the proper sequence for spark control. CID is also sent to the EEC-IV micro-processor to allow for Bank to Bank fuel control. Failure Mode Effects Management
During some DIS system faults, the Failure Mode Effects Management (FMEM) portion of the DIS ignition module will maintain vehicle operation. If the DIS ignition module does not receive the SPOUT input, it will automatically turn the ignition coils on and off using the PIP signal. However, this will result in fixed spark timing (ten degrees BTDC) and a fixed dwell time (no CCD). If the DIS ignition module does not receive the CID input during engine cranking, random coil synchronization will be attempted by the module. Therefore, several start attempts (cycling the ignition from OFF to START) may be required to start the engine. If the DIS module loses CID input while engine is running, the module will remember the proper firing sequence and continue to fire to maintain engine operation. Dual Plug Inhibit
Dual Plug Inhibit (DPI) is a function of the EEC-IV that is only used when the vehicle is being started at temperatures -7° C (20° F) and below. During engine cranking, the EEC-IV will only fire the spark plugs on the right hand side of the engine. When the engine has started, the EEC-IV will send a signal to the DIS module to start normal dual plug operation. Ignition Diagnostic Monitor
The Ignition Diagnostic Monitor (IDM) is a function of the DIS module. The DIS module sends information on system failures to the EEC-IV which stores the information for diagnostic self test. The IDM signal also is used to drive the vehicle instrument tachometer, and test tachometer for system

Ignition module where do I find it.


The ignition coils are mounted on it. Just follow the spark plug wires.

Where is the coil pack located under the hood


Follow the spark plug wires away from the spark plugs. The coil packs are on top of the ignition module. The coil packs have two terminals each and will have two spark plug wires attached to each coil pack. There are 3 coil packs and I would recommend replacing all three at once. They are bolted down to the ignition module bracket with a total of 6 small screws. Two per coil pack. Remove the small screws and the electrical connectors and the plug wires. Dont forget to mark the wires so you can replace them as you found them. Installation is just the opposite of removal.

Engine loss power good fuel but no spark at coil or plugs


Check the grounding surfaces on the coils. Also, check your ignition module, it may be malfunctioning.

Many coil problems are actually caused by other malfunctions.

I'd go ahead and change the plugs and wires anyway since it's always a good thing to do. I'd definitely start checking connections on the coil pack and ignition. It's most likely a problem somewhere in that range.

I hope this helps a little. Spark problems can be led from many different areas.
