1997 Chevrolet Truck Repair Question
Mileage: 15,200 miles.
I have a 1997 chevrolet 2500 that wont start the pcm/vcm keeps blowing {ecm-b} fuse
Asked by sherriesuexoxoAnswer
under the dash, left side.
first, i would remove the connectors from the pcm and re check the fuse. there are many things on the circuit and it may be another load or bad wiring. the pcm is an expensive guess especially if you are wrong.
Roy
where is the pcm under the dash what does it look like
behind the glove box door. it is about 6-7 inches square with 3 connectors on it.
Roy
could it be anywhere else because im not seeing anything but the blower motor heater what else could make that pcm/vcm[ecm-b} to fuse keep blowing and the truck will not start it ran fine and all the sudden it died and wont do anything
i believe the fuel pump is on the same circuit. try disconnecting it at the tank and see if the fuse still blows.
Roy
ok, look harder behind the glove box for the pcm. it is there.
Roy
ok i found it how do i no if its the problem it looks like its fine
looks mean nothing. remove the 3 connectors and try the fuse again, if it blows, then it is something else and you need a shop to track it down. if the fuse holds, then it is a shorted pcm and needs to be replaced.

I just wanted to thank u so much found the problem it was a pinched wire Thanks so much again.
