Re: GMC wont start
Was crankshaft variation learn procedure performed after replacing the crankshaft sensor? P1336 set?
First place to start is check for spark out of the coil.....
If you have good spark, then the distributor is not timed correctly......P1345 may be set......
If you don't have spark, then you have to make your tests at the coil harness(term C, white/blk wire) to see if you are getting a coil trigger signal out of the EICM, and then if you are getting a trigger signal at the harness(term B, white wire) to the EICM from the VCM.....
If you need this test procedure, I can print it for you....
If no spark, and no trigger signal from the VCM, chances are it's a crank sensor/harness/wiring problem.....
