OK, motor is in, everything is swapped over to odbII, fuel is delivered correctly, motor is turning over but no spark, computer is also throwing the DTC P1336= "CKP System Variation Not Learned" I have changed the coils, plugs, wires, CKP sensor, Ignition Control Modual, still no spark, Ive checked the power going into the ICM and it read 12v, checked the wire coming out of the ICM and into the coils, 12v. checked the bridges on the coils while the motor trys to start and it reads 5v. idk wtf the problem is, im lost and this is my first swap so idk what to do... please help
you need to go to the GM dealer and have them perform the crank position sensor learn procedure. its a mandatory every time the crank sensor and/or crank, and/or PCM has been replaced.
Ive looked at the learn procedure and it says that the car must be running in order to do the procedure, now i hooked up a vtmeter to the purple(+) and yellow(-) wires, the meter didnt move at all, even tryed to switch the wires, still nothing, not even the required 5v, and its a new ckp sensor as well, I unclipped the plug to the DIS and the CKP sensor and hooked up the battery to the wires and it prooved the wires were fine. so idk wtf is going on.
Can anyone think of anything that could be wrong?
Does it not start at all, or start for a second and then shut off right away? Still using the keyswitch from the 95?
And yes the engine needs to run in order to do a CASE learn, so that'll be later. I don't think you'll see anything on a DVM from the crank sensor. An analog one maybe. A oscilloscope would def. see it. I would guess possibly also just a bad ground to the ICM, or a fubar'd ICM.

you run the risk of throwing the ckp variation code as well as a false positive random cyl misfire code
It wont run at all. ECM should be fine its brand new from autozone and reprogramed for a 98 z24 cavalier.
Ok... but that will still need a case learn once it is running.
But the ICM is what I'm looking at. If it's like the ICM on the other cars like the 2.2, and all the v6's then it should be able to give spark without the ECU telling it to do anything at all. You'd just have 0 timing advance and no power, but it would run.

ive tryed 3 different ICMs
is there a way to test the ICM?
