1999 E350 blowing fuel pump fuse

[chet]

I have a 1999 powerstroke 7.3 that keeps blowing the fuel pump fuse. This even happens when the fuel pump is disconected. Any ideas?

you have a short. trace the wires from the fuelpump back up to the main conector at the firewall

a rfeind had the same problem on his 00 f250 it turned out to be the relay..I think he said the glow plug but not sure..so check out your relays...

use a 12v light bulb, like an old tailight socket, with long enough leads to see it. the bulb provides resistance, won't burn anything, and when you wiggle the wires and find the short, the light will flicker or go out. if you have an intermittant short, you can use a seatbelt chime, wiggle away, and listen for it when you wiggle and cause the short.
