I'd replace the ECM (electronic Control Module). These are often the problem on older GM vehicles. It's fairly simple to replace. It's located directly under the distributor cap and rotor. Costs about $60 for the part.
Spark as in the ignition or spark as in not starting? Please be more specific and we will try to help you.
ignition switch The TDC Sensor is probably dirty, remove it and give the tip a clean, also the connecter.
what are you trying to measure and with what type of meter? generally we check the module with a spark tester. if there is no spark with the spark tester we check the kill wires and any safety switches that may cause a no spark issue and if all that still shows no spark then we replace the module.
Control Module depending on type controls the engine functions, transmission, ignition, etc. (test does not specify "Ignition Control Module")Starter solenoid would be the most likely choice because on older vehicles with points ignition, the solenoid has a Resistor (Run) post for and an Ignition (Start) post, but now we don't need resistors, but it still has to do with ignition!Coil supplies voltage to the spark plugs = ignition again.Spark plug creates the gap for the spark that the fuel needs to ignite, ignite = ignition.
Change crank shaft angle sensor ul get a spark
== == check that you are getting power to the distributor. i am assuming you are talking about a earlier model vehicle Have you checked the ecm relay? maybe the pickup coil assy.
I don't know I'm also still searching the answer for this question.
I would replace the ignition module in the distributor.
A CDI, or Capacitor Discharged Ignition is a system that is linked to the ignition of some petrol engine driven vehicles. Its purpose is to store an electrical charge that is discharged through the ignition coil and thus increases the power to the spark plug/s for a very powerful, high-energy spark. This prevents fouling of the spark plug/s. A CDI can be disconnected in some vehicles and the engine would still run, but with a less powerful spark to the spark plug/s.
I have an 89 Ranger with the 2.9L, was driving on the highway and it just quit. I thought it was probably the timing chain, had it towed to a shop and he checked fuel pressure which was normal, found no spark condition. He tested the ignition coil, pickup coil, module and wiring for faults. Failure traced to the ignition control module. He also replaced the distributor cap, rotor, and coil wire. If you have a no spark condition I would recheck all these because I think if it is a broken timing chain you would still have spark. The ignition control module is at the base of the distributor cap. Assuming your ignition coil and ignition control module are good, try the pickup coil. Stay with the ignition system until you get spark. i have the same problem with my 88 ranger changed distributor, rotor button, ignition coil, and tfi module, still no spark. If it is the timing chain it will not spark.
It happens. Just b/c you have a spark doesn't mean it's hot/strong enough to reliably ignite the fuel.
your coil packs are bad. this is not cheap to fix. sorry.
After testing the coil for proper resistance and finding they had the proper values, I swapped them from one side to the other. The coil with no spark still had no spark. A new coil was installed, problem solved.
I would suspect the coil itself, even with the wire connecting to the distributor cap removed, you should still see a spark from the connector on the coil to the body of the coil itself
I have a 99 Sable with the OHV 3.0 liter. I have the same problem. Things I have changed so far: the engine computer or (PCM) , the crankshaft position sensor, and the ignition coil. Still have NO spark to the engine. The spark plugs don't spark. I am still waiting for more info. Let me know if you have changed something I haven't. Thanks.
If just the fuel pump has failed you would still have spark. But, you could have serious electrical problems that caused multiple problems that included the fuel pump circuit and the ignition circuit to fail.
Plug wire, distributor cap, or rotor is defective.... You may need to set/replace the Ignition Breaker Points and the Condensor, 1964-1973 Ford still used ignition points and condensors in several models including the mustangs...
The thermocouple is usually the first thing to change. It controls the valve and the spark ignition is just to light the pilot.
Check to see if it getting spark/fuel Check rotor
Your car is still running after turning off the ignition due to a phenomena called dieseling. The gasoline in the cylinders is igniting without a spark from the spark plugs. You are having carbon build up in the combustion chambers and it is raising your compression ratios. You need to go to a higher octane gasoline until the problem is fixed or fixes itself.
if you are not getting spark in your coils iti could be the crankshaft sensor im not a mechanic lol but i have the same problem with mine im trying to find out how to install the sensor i replaced the coils and the ignition module and still no spark
Well sometimes the radio is hooked up to the ignition itself. It is just the ignition wire, if it has a disconnecting face plate then you can turn it off by taking the face plate off. Or if you would like, you can pull the radio out and disconnect the wire from the ignition and it will not still be on when you cut the truck off.
Pull out a spark plug, rest it on a piece of metal under the hood, have someone crank the engine, and see if it sparks. If not, check for a spark at your ignition coil by doing the same thing. If you still have no spark, check your distributer cap and rotor, they may need replaced, or the whole distributer may need replaced.

sounds like we are having the same type of issue, I replaced ignition Module and coil pack, and still no spark the last thing to change is the Computer.
