2001 Cavalier Z24 Won't Start!!!
My Z24 won't start all of a sudden. The battery is good. It cranks over, it's getting spark and fuel. It won't start still. I replaced the fuel pump, fuel filter, air filter, and spark plugs and it still won't start.
The ICM is getting power and is grounded. I couldn't test the 7X reference signal or or the 1-4 and 2-3 coil control signals because I don't have a test meter with Hertz capability. The crank sensor resistance seems to test okay.
What could it be? I'm thinking that it could be a sensor, but I don't know which one...

theft deterrent indicator on? any dtc set in the pcm or bcm?. If your getting spark the cam and crank signals are probably working, but yeah, check it if you can.
If nothing turns up out of order a compression check would rule out mechanical engine problems.
