fuel pump doesn't get signal - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I finally got everything done and hooked up on my car. But there is no fuel coming into the engine. I took the line off and there is no fuel coming in. I checked the plug with a voltmeter and am getting no signals. Does anyone know which line it runs off of? Then I can check the connection.

just to make sure.... did you check the fuel pump fuse??

justeno_heat · 05-07-2003, 10:39 PM

yeah I did, the fuse was fine, there's got to be a bad connection in the harness somwhere.

sounds like a good bet..... is the fuse getting voltage also?? that might narrow things down slightly. You should also check the fuel pump relay, which on the S14 at least is located to the left of the fuse panel.

I didn't see any fuel pump relay to the left of the fuse box anywhere. I tried checking for voltage to the fuse but I don't get any for even the horn that does work. So I don't know. All I know is that the whole box is getting juice.

If you could describe to me where the fuel pump relay is at on an S13 I might be able to fix it. I think that is what it is. I was looking at the wiring diagram and it points to that.

im having the same sort of problem

wondering if anyone knows where this relay is?? There is voltage at the fuse for the fuel pump but i think i should check to see if the relay is bad too before i go get the pump changed

any one?

I'am 95% sure its the relay. Do what I would do, follow the wires from the gas tank, you're bound to run into the relay
