I have a 2001 Chevy venture that won't crank or even try to. All the gauges come on and work, along with the hvac controls and radio and all that stuff, but turn the key and nothing. Battery is fine, all fuses are good, however... several fuses are not RECEIVING power. They are not actually blown. Have to check what each one is, i know one of them is for the fuel injectors. This all happened when i was wiring up a fan toggle switch and i think something touched while working in the fuse box, cause that is when this started. I when on a whim and replaced the ignition module with a used one, and that didn't change anything. I'm starting to think the PCM got fried, and i assume a used one would have to be reprogrammed. Are the PCM's in the intake air box on these? Any input or other ideas would be appreciated.
