SOURCE: blows fuses

Generally speaking, a fuse 'blows' because too much current is drawn through that circuit. In this case I suspect a 'short-to-ground' or a bad voltage regulator (inside the alternator in a GMC). First, I would check the alternator's output voltage. Easiest just to look at your guage. Up to 14 1/2 volts is normal on a GM (with truck running), if it's higher - you need a new alternator. If it's under 14 1/2 volts, you
MUST find the short. Unless you have the specialized tools, (short-circuit finder, voltmeter, wiring
diagrams, etc.) this should be left to a competent automotive electrical shop. It could be as simple as a wire's insulation worn off or a short 'inside' the ECM (you truck's engine control computer). No matter what, one trip to a competent mechanic will probably be cheaper than continually replacing the computer and/or towing bills. Good luck!

SOURCE: I have a1994 gmc Sonoma. Fuel pump fuse keeps

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.

SOURCE: I have a 1991 GMC

ECMB fuse it is hot at all times and sends power to the ECM ( computer cavities c15 and b1), oil pressure switch (to power the fuel pump when there is pressure) and the fuel pump relay. All orange wires.
So while checking those items also check the fuel pump and all their circuits.
I think the last person that had this problem had replaced the fuel pump and that fixed it.

I got this info from a chevy truck owners forum and also researched other other sites, the most common thing to blow the ECMB fuse is a shorted fuel pump or fuel pump circuit wiring, disconnect the fuel pump at the tank, if the shorts stops and fuse dopesn't blow replace the in tank electric fuel pump.

Starting problems


With a voltmeter or test light can you check for power at the fuse block? There should be power to some of the fuses like ignition or radio, cigarette lighter. If not then check directly at battery. Some cars have fusible links between the battery and all loads, I don't know yours.

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.
