New PCM - car will not run.
does anything need to be done to the PCM before its placed into service?
car is a 99 Camaro w/ a 99 LS1. installed a Painless harness for a 98 w/ a new 98 PCM. i have a VATS module from Baker Electronics on it. the car will not run.
lets not get into the why part of things, i just need it to run.
i verified F/P today as well as spark.
any difference in the Can Position Sensors between 98 and 99?
no. does that have to be done?
i also put a noid light on the injector plug, and it looks like the injectors are NOT firing.
i have spark and fuel pressure and no injector.
looked up a PCM for a 98 Z and it says requires programing before use.
ACDELCO Part # 16238212
MODULE,Powertrain Control(REMAN) REQUIRES REPROGRAMMING
i put the 99 harness and PCM back in, and put power and VATS where it was needed and it fired right up. Painless harness and 98 PCM going back Monday.
Jegs sent me the wrong harness so i ordered a 98 PCM to try and make due. never again. using the OEM harness is just too easy.
By the way, this is for a roadrace car w/ a full complement of autometer guages.
