Question about 1995 GMC Sierra C1500
Will a bad fuel pump cause the ECM 1 fuse to keep blowing?
Ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
this is for the fuel system, relay for the injector is nearly the same.

SOURCE: Fuel pump fuse keeps popping
You have a short to ground or the pump is starting to go bad. You can run a seperate wire from the hot side of the fuse to your pump to see if it is the pump or if you use an ohm meter to check the wire and the pump. Get's a little technical though.

The fuse is actually a Relay Switch and its located in the Fuse Relay Center on the driverside of the engine compartment. The Black Box is labled Fuse Relay Center, the diagram on the cap displays which Relay is the Fuel Pump relay...the Relay switch is usually $8-$15 depending on where you shop

The only other things on that circuit are your PCM(power control module) and the fuel pump/oil pressure switch. You can start with that but it is more than likely a ground somewhere on that circuit. If this helped four thumbs up please.

the heater tap on the return end line of your injector rail.. could play a part. and all the injector fuses and relays are good too??
