I have an 02 Ls1 Camaro. Ive disabled the VATS but every 6th or 7th time I try to start the car it wont do anything. I can pull the fuse under the hood IGN PCM 15 amp fuse and in about 3-5 minutes it will start. Any ideas of what could be happening? I can start the car with a key with no chip. So the VATS is off. Just don't know what else could cause this. Any help Appreciated!
