I was off-roading at some sand dunes, hits a couple big woops before going up a hill and then the the truck stumbled and shut off.
heres the problem after a few hours of diagnostic is that there is no power at the pump and I am only getting about 4.5 volts at the fuse
Things I have done;
- checked, reset, and bypassed the inertia switch
- replaced and bridged to pump replay.
- jumped and bridged to fuse
- checked for any broken wires and re-wired a ground wire for the pump.
Any attempt to get power going to the pump has not worked. I have pulled the pump and jumped it straight off the battery and it pumps fine... it should, its only a year old.
like i said though, there is only about 4.5 volts coming into the fuse when you turn the key on... ALL other fuses have 12.5 volts, the fuel pump fuse is the only one low.
My only other thought is the ECU shit the bed or something
Anyone else have and ideas.???
EDIT: Sorry, truck is a 91 GDE
