Truck won't start. Know replacing fuel pump will be a b$*&# because it's in the tank. Where is the relay? Any options to bypass in-tank fuel pump with a replacement? i have a 1988 chevy silverado 5.7 ltr and it will not trun over, what other option do i have besides replacing the fuel pump
Yes typical problem and know about the pain in the #$#$ about getting the tank down.
The relay is under the hood and in the relay box. Quick check the fuel pressure on the injection rails.
Yes you could add an inline fuel pump to the line and see if that would create enough pressure. I do that on my race cars.

Check in relay box on passenger side near firewall for fuel pump relay.
By -pass, no such luck that I' aware of, sorry.

the relay and fuse are in the power distribution box under the hood. as far a by pass you still can use an aftermarket electric pump ,however the cost will be about the same as re3moving the old pump in the tank if that is the cause in the first place. if all you need is the relay replaced then i'm sure that the pump is still good. if the pump is bad then make sure if you by pass the in tank pump that the new under hood electric pump has enough pressure to give the needed gpm(gallons per minute) required for your system and that if wired into the current fuel circuit that you dissconnect the wire harness to your tank pump
