1999 chevy blazer will not start. No spark!?!? No spark from the coil to ground.


Could be a bad coil, bad Ignition Control Module (what controls the ignition coil as commanded by the engine computer), or a bad crank position sensor, or cam position sensor. Or the wiring and circuits to all the ignition parts.
Often it is the crank sensor (CKP sensor)-The pcm must have this information from the crank sensor to determine spark timing. If no good signal from the crank sensor, there will be no spark.

I need help locating a module ignition modulator in a 2003 Chevy Tahoe


Who told you that one ? Module ignition modulator 2003 Chevy Tahoe ! No such thing! Your best bet would be to take your vehicle to a qualified repair shop .
The electronic ignition (EI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system consists of a separate ignition coil connected to each spark plug by a short secondary wire. The driver modules within each coil assembly are commanded ON/OFF by the powertrain control module (PCM). The PCM primarily uses engine speed and position information from the crankshaft and camshaft position (CMP) sensors to control the sequence, dwell, and timing of the spark.

NO FIRE TO THE SPARK PLUGS, I CHANGED THE MODULAR,COILS ,PLUG WIRES ,PLUGS , 1997 CHEVY LUMINA 3.1 WHAT NEXT ?


Check for the presence of voltage to the coils and the ignition control module. The ignition switch may not be supplying power in the crank position.

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.

I had the same problem with my 85 cj7 this week, I relpaced the ignition control module, plugs, wires, cap, rotor and the the coil; still had no fire to plugs. the problem turned out to be my distributor, replaced it today and she fired right up. Most likely it was the pick up module in the distributor that went bad.
