1997 Chevrolet Truck 2500 That Wont Start PCM Vcm Keeps Blowing ECM B Fuse

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

yes it still blows the fuse

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.

way to stay with it. good for you. it is our pleasure.
