94 3.4 v6 Camaro NO SPARK URGENT!!!!!
#21
Back towards the trans? I see that the hot wire that feeds this is also feeding the 3x and 24x sensor. Maybe a few other things. Imma check and see if there is a short near these connections. If there were.... Theoretically it could cause this no start no spark condition. I went to my local reputable mechanic and looked at some diagrams on his computer and we are Sure this is the issue. Thanks for you help so far crabby

Im sure they were in there... I just couldnt find what i was looking for. I see that the hot wire runs a couple things. 3x ckp, 24x ckp and cam sensor. Ive replaced the 3x sensor but not the 24x or cam sensor. I need to test all the connector plug ins for continuity. I noticed no difference in voltage with all the corresponding connectors on the circuit disconnected... I figured faulty sensors could short the connection but theres no difference with them disconnected

Ive thought about that... Do you reckin a wire in the lock key cylinder may be frayed causing that? Occasionally my security light will flash and not accept my key.. Maybe because of a loose wire? I took out the panel below the steering wheel and looked for frays. Though not a thorough inspection, i didnt see any burnt wires.

If it were the ignition switch, would the car still crank strong? I think the power wire is grounding somewhere. Why would that wire be ylw and not pnk? If the wire was spliced, it was done well into the harness because i cannot find the split.
If the car would still crank strong with a bad ignition switch, then i will pursue that option.

Wellll... I jumped the wire.
Did nothing but spark.. And i found the problem shortly after. Apparently theres a sensor relatively close that uses the same connector. Id say silly me on reconnecting the throttle body harness wrong.. But i hooked up bottomside. Looked over the wiring diagrams, found the pnk and black connector, and put em in their corresponding positions.
Now, im not saying that the pcm got fried...
But essentially we jumped a 5 volt ref with 12 volts.
Worried.
I atte.pted to crank with a jump vehicle and still got no spark. However battery is dead as can be. Hopefully thats why.
Either way... 1 step closer.
You cant hire good help nowadays. Joking..
