Good morning, I have a 1995 Astro 4.3. The PCM fuse popped a few days ago...which of course also powers the Fuel Pump Circuit. I have good factory wiring diagrams on this... I am not sure where to start troubleshooting...My instinct is to power up the Fuel Pump Circuit direct from the battery with a
5 or 10 amp fuse and see if that fuse pops before the PCM fuse...Before I start cutting wires and heading off on the wrong path...I thought I would ask you experts if you have any suggestions based on your experience which might be a common fault with this circuit that I should check... Thanks, Cory
