    I have a 1991 chevrolet Suburban that keeps blowing the ECMB fuse.  I rewired from outside the fuse box to the fuel pump and unplugged the fuel pump, but fuse blows immediately when I switch on the key.  Any ideas?

I had the same problem on my other 'burb ('90 2wd with same engine).
after dropping the tank ( about 5 miles after i filled it up!) because i thought the pump had cooked, i figured out the fuse had popped, and kept popping occasionally after that. i re-ran the wiring to the fuel pump, and this fixed the problem.
i checked the old wiring for any short/break in the wire, as there was not any visiable signs of a short, but still couldn't find anything concrete to say "this is where the short was!". but, it didn't matter, since the replaced wiring never gave me an issue and i didn't have to replace another fuse again! good luck brother.

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.

Keep blowing ecmb fuse after replacing fuel pump

My guess is to recheck the work done on the vehicle. I believe a wire is pinched and grounded.

ECMB fuse keeps blowing on a 88 S15 pickup. I have replaced the fuel pump & the fuse block but my fuel pump still doesn't work

Un plug the Computer to see if the fuse doesnt blow now. You may have a short in the PCM or the harness.
