Ecmb fuse keeps blowing on my 99 s-10 put new fuel pump in about a month ago and worked great since then but today it shut off and blew the fuse again not sure what to look for.


Well that circuit powers the memory for the computer as well as the fuel pump relay and other things.
You might be able to pull the pump relay and see if the fuse still blows, it will be tough to find the problem if it is at random times.
You'll probably need a shop manual to get the wiring diagrams to trace it.

Keep blowing the ecmb fuse in my 1991 s-10


check your grounds & the fuel pump connections.the ground should run to the right rear of the motor. look at the wires back to the motor on the frame for anything that may have nicked a wire or a rub thru. You have a short and i belive it shut down if you hit a bump. loose or fraid wire some place. Best of luck & keep us posted on your fix.

No power to fuel pump and the ecmb fuse bows as soon as i put it


Unplug all wires to the distributor, coil, fuel pum and injectors, then see if the fuse blows, if it does, sounds like an ECM failure.
