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.

If it "keeps" blowing the ECM fuse, it is because you "KEEP" replacing the fuse without diagnosing and repairing the reason the fuse is blown.

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.
