hello, just wandering if anyone else might have an idea as to whats wrong with my truck. its a 97 chevy silverado 4x4 350 automatic. its got 194,00 miles and ive had to fuel pump replaced twice in the last 3 years. the latest is about 3 months old. the problem is the fule pump relay keeps over heating and causing the truck to shut off. i have a fuel psi guage on it and i can see it drop to about 40 psi and it wont run. i bought a new relay and stuck it in there and it worked good for about a month then started up again. when its working the psi is 60-63. any clues as whats going on?

thanks in advance, j

 

I'd say check the fuse for the fuel pump circuit and make sure it is the correct amperage. Other than that I would say to check and double check the fuel pump circuit for bad wires. What brand was the first fuel pump you replaced the OEM one with?

 

thanks for the tip. fuse is ok. i did find the wiring to be burned up underneath the fuse/relay center. i repaired that and have not had any trouble yet. im not sure what brand it is in there. i had midas do it for me cuz it broke down about 50 miles away from home. oh well,kep on truckin!
thanks, j

 

Welcome.

That should solve the problem. Not uncommon for relay wires and harnesses to get burnt up or corroded in vehicles, even newer ones.
