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.
ignition switch The TDC Sensor is probably dirty, remove it and give the tip a clean, also the connecter.
have you replaced and or tested both coils? are you getting no spark on the intake and the exaust sides?
Are you talking about the electronic ignition module or the ignition switch? The ignition module sits in the engine compartment and is part of the ignition system (coil, spark plugs, etc). The answer is no if this about what you're referring. The answer for the ignition switch will depend on the vehicle you have. Some, like late model Fords, you don't. Push in the retaining pin and the ignition switch comes right out (you still need a key though). Others you need to take off the steering wheel to replace the switch.
AnswerCould be a bad ignition switch. or Timing is off. This is known as dieseling. The car runs off combustion and burned gases still in the cylinder even if the ignition is off. Make sure marks are lined up on the camshafts and crankshaft. mostly likely have to remove the valve cover to check timing. Even though its a chain timing can still skip a mark. Another thing to do is make sure the piston is on top dead center and the dist. is firing on the number 1 cylinder.also try Removing the spark plug on number 1 and have someone turn it over as you watch for a spark.
You didn't mention whether you've changed the coil wire itself. If it's faulty, you'll get no spark anywhere. Also, the power supply to the coil or module could be at fault.
Spark as in the ignition or spark as in not starting? Please be more specific and we will try to help you.

map sensor
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.
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.

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.
your coil packs are bad. this is not cheap to fix. sorry.
