I have a 1997 S10, it has about 135 k miles. I have replaced the fuel pump 2 times, the current on is not getting any power. The fuel filter has been replaced. I am not 100% sure which relay in my Glovebox is for the fuel pump, I'm not sure just where the problem is. When I installed the current fuel pump it did not work, after about 2.5 hours or so it finally did start to pump, the next day I started the truck and it worked just fine, turning the truck on and off about 3-4 different times, it finally got to the point where it didn't start / nor did the fuel pump start to pump fuel. I am growing too many grey hairs over this issue. please help.

Thanks

 

i dont know where the fuel pump relay is on an s10 but that sure sounds like the problem here. have you put a guage on the fuel rail and checked your pressure? have you checked all of your grounds? a service manual will show all the locations for grounds and the location of your relay. i believe they can bought directly through helm.
