Fuel pump

[hazzzy]

Ok I have a '92 Honda hatch with a fuel pump problem. The pump dosen't turn on when hooked up with factory wiring but if I run a wire from my under dash fuse box that is a key on it works. Just wondering if there is a fuel pump relay anywhere that might have gone bad. If anyone has any ideas let me know.

I very well could be wrong, but you may not have a fuel pump relay, if you know the pump is good, then I'd be willing to bet there is an open in the factory harness, or a bad ground....

I had this issue few years back with my parents old civic and I couldn't figure it out for the life of me, but i did end up narrowig it down to either te ecu wasent being ground or the pump went out I would go over all grounds and pull your ecu and start chaseing your wireing down with a meter to see where the power isn't getting to your pump

the fuel pump relay is part of the main relay here.

Did you check all the fuses?

Checked everything just didn't know if it had a different relay for the fuel pump or not.

pgm-fi relay is the only one.
