Default 93 Suburban K2500 5.7L TBI Fuel Pump Fuse & Relay location - 10-17-2007 , 05:00 PM






Can anyone tell me exactly where to find the electric fuel pump fuse
and relay for the above truck? Also, which pins to bypass on the relay
for a test? I parked it and it is no longer getting fuel (did a fuel
pressure test and got zero). I want to rule out the electronics before
I hire a truck to haul it out of the parking garage and 20 miles to
home since I don't think they'd like me dropping the (1/2 full) fuel
tank in the basement of my workplace.

I looked under the hood and saw no obvious fuses or relays for the
fuel pump. I assume such a thing would not be in the interior fuse
panel, though unfortunately I no longer have the owners manual which
might tell me about it.

Thanks in advanced if anyone knows this information.

Aren't they on the passenger side firewall under a black plastic
cover? That's where the relay is I think... also I believe there
is a fuse in the fuse panel for pump too.

I don't know the test off hand but it would more or less entail
hot-wiring the pump to see if it works, bypassing the relay.
I think the relay is around $20 or so at NAPA and the fuse would
be easy to check. I would just swap out the relay first.
