if anybody has any input on this i would greatly appreciate it. i used to own a 99 gt and never had any problems then some body t boned me so now i own a 01 gt that is a bitch to start in the am when it is cold i have no spark and i am not sure if i have any injector pulse but i do smell a hint of gas but if there is no spark i doubt the injectors are firing so here is what i have done so far

-replaced crank sensor
-swapped ignition modules
-tried the 99 pcm but the 01 doesnt like it
-i have tried all of the security procedures but once it is warm outside it starts and runs beautifuly
oh and i even tried taking the pcm into the house for the night so it would be warm

well i decided to check the cam sensor and found bare wires so i replaced it and actually runs a little more smooth and i just tried to start it since it kind of cold and it worked so ill keep my fingers crossed for the morning

I like the taking the pcm in for the night ideal.

But wires can be a pain in the ass. My car stalled in the stall in traffic in the past when I had a bare wire problem to my control module. It would only do it once the wires got hot and soft. . they were possibly touching. Fixed it and no more problems. . . .. like that anyway haha.
