How is crank position signal read? What on the crank does the crankshaft position sensor read off of? Magnet?
My car is having issues and after replacing the pcm,crankshaft position sensor, inspecting wires and doing ckp relearn it still has hard starts and when it runs it will notmove if you give it gas it just backfires violently.
Codes it keeps setting are p0327,p0332,p0336. None of the wires are melted.
My only other theory is that whatever the ckp sensor reads off the crank might have come off or is damaged some how.

yes, it is a magnet (called a Hall-effects sensor). its basically just a metal circle with notches cut in it so that the computer can know where top-dead-center is.
i know that when there is a problem with the camshaft position sensor it the computer puts the injectors into "batch fire" where it fires the injectors at random times hoping that it can get fuel into the cylinder when it is supposed to be. as a result the engine doesn't run very well at all, and runs VERY rich. it kinda sounds like thats what your car is doing.
