Hey guys i got a 97 silverado and my fuel pump stopped working. So i replaced my pump, sending unit and relays because they were all wore out, however im still not getting any power to my pump when i turn the ignition on... any ideas on what the issue may be?

 

well there are several things that come to mind right away...the main one being ignition switch.....I would start looking at the wiring in the steering column.

 

Could be ignition , fuse , Bad ground at tank, was it running any before changing pump ect? Need to start from tank forward for bad wires , grounds ect. Reason i,am asking
About running a bad pick up module , oil sending unit if bad can cause this.
Even if your low on oil fuel pump won,t work. Need to get you a test light start testing first no need to buy stuff .

 

try swapping the fuel pump relay with another relay

 

ive tried dwitchin my relays and there still wasnt a response, truck isnt registering and DTC's so im not sure where to go from here very much... also my alternator was shot and so afterward my fuel pump started giving me problems (acting as if i was running on fumes even tho i had a full tank). after replacing the alternator there was no activity from the pump. could this possibly be playing a role? thank you for the input
