1997 GMC Jimmy Turning over but no fire!!!

The wiring circuit for the coil driver module, is it factory? Check the circuit, pink wire is B+, white wires should have a pulse with the engine cranking, black is ground.

i changed it, its new. there is fire to the wire going to the coil but no fire from the coil to the distrubutor!

i am trying to get a mechanic over to put there computer on the Jimmy to see if it will tell us anything. still waiting on the mechanic! i dont know if it is even going to help since it has never started. hope i get something figured out soon! i really need my vehicle right now. i have changed many motor by my age of 27 right now and i have never had all these problem's, its normally just a cut wire. i just dont know anymore. help someone please!!!!

Check out ignition Control Module located top left side engine on valve cover. It fires coil via PCM

i changed that part with the new distributor, rotor, and cap i put. the connector for the neutral safety switch would not come out and it cracked the the switch so i got a new one and just noticed my connector with the 7 wires ( looks like the wires go to the computer and distributor ) has a few bare wire, i dont think that would stop it from start hun! i am ordering a new connector to put on the switch, going to take a few days though!!!!

i have a Chilton book on my Jimmy and have been reading and testing everything it shows me and still nothing. i have been going through the troubleshooting scenarios for will not start and it is not giving me any useful info.

i changed the neutral switch on the transmission and now if i try to go through the gears my Jimmy tries to start in OverDrive. Now the key is not being turned to start the motor, the motor is just turning over by itself when i shift the vehicle in OD. HELP!!!

the transmission switch was defective so got a new and that part is working. now i found out about the refluctor plate that goes behind your timing chain cover to let your cam sensor send fire to the motor was left on the old motor. now Chevy Dealer said i would need to pull the motor out of the Jimmy to change the part and they lied. i changed it without pulling the motor, just had to take off the 3 front bolts on the oil pan on each side and it was not easy but i was able to fix what i needed and now my jimmy is running. hope my problem can help someone else or even make them aware of the refluctor plate because it fires the hole motor.

Ouch! dealer gave some bad advise. Glad you solved on your own. Great info reluctor left on old engine ran into that on Pontiac year ago wish I would have had better memory.
Good Luck
