How do I test the fuel pump on a 1992 honda accord?

Asked Mar 18, 2007, 05:53 PM — 2 Answers
How do I test the fuel pump on a 1992 honda accord? On other models there is a way to short the pump at the relay and you can tell if the fuel pump is working or not. Is there a way to do this on the 1992 honda accord lx?

First, turn the ignition to ON and listen for the fuel pump, in the gas tank, whine. Second, disconnect the main relay and jump terminals 5 and 7. When you turn the ignition to ON, you should hear the fuel pump run. Let me say very few Honda fuel pumps fail. Most of the time they are replaced by mechanics who "figure" it must be the fuel pump, when it really isn't. Often, the problem is with a fuse, main relay, or ECM (preventing the main relay and fuel pump from operating properly).

See if this helps:

Ultimately, reading sections A and B will likely help:

I'd begin by testing all under-dash and under-hood fuses with a test light or multimeter. Then, I'd run the K-Test on the ECM.

Crack the nut on the fuel rail and crank engine. If it sprays out ,it's ok.

My Accord won't turn over when the weather is hot or when driving it for period, parking and returning a short time later. (i.e. Running into the store for 3 min). I heard it might be my main relay? Never a problem during cold weather.
