There's no fuse for it the PGM FI main relay powers it when the key is turned on here is a guide to help you test the relay and diagrams below to show you the location.

Relay is good checked several times pump does not prime however provides pressure when cranking ecm comes on energizes relay after some time tinkering I decided to look for a grounded fuel pump. Internally grounded as I have had an issue like this with a different vehicle. Removed 3 pin connector at fuel pump. Probed the yellow wire which supplies twelve volts to the fuel pump this test was done with harness d/c at the fuel pump between yellow wire and ground I have approx 50-150 ohms.

I have a '91 Honda Accord that quit working while driving down the road. I have replaced the battery, alternator, spark plugs and wires, distributor car and rotor button, and the ignition coil. The car will cranks and turns over easy, but will not fire. We do not hear the fuel pump turn on so wanted to check the relay the the fuel pump. Where is the fuel pump relay located on a '91 Honda Accord? And is the fuel pump in the gas tank?

The PGM-FI main relay powers the fuel pump and the fuel pump is in the fuel tank

Dunno the total resistances of the fuel pump motor windings-as you've check it and its 50-150 ohms

Do this power the fuel pump direct from the battery and see what happens

Ok just a hick update sorry took so long to get back here.I pulled injectors have great spray all four plugs firing. Firing order correct. Manually cranked engine by hand to ensure distributor seated correctly it is.S light stopped blinking. Still no start checked ect. Tps. Iat. Seems like my map sensor isn't showing correct return voltage for 0 in/hg only have.19v returning which appears to be what it should read at full vacuum.I don't have a vacuum pump so I can't test other voltage readings.I think I am going lil crazy here thanks for your time PS bout 150 psi per cylinder compression I really am losing it this is the second new distributor I put in because the first one I got had a bad reluctor.I am sad

This accord has a habit of not starting when the fuel level goes below half a tank. Above that no problem, but as soon as it gets below that mark it will die or if you turn it off it won't start again. Changed fuel pump, cleaned tank, replaced fuel filter, replaced pump relay. Any help would be appreciated. Not much hair left on my head from this one. Thanks. Tigerguy05

If the fuel sending unit has been changed and it is new, the nest suspect will be the coil behind the gauge or the wiring from the fuel tank to it.

I should have mentioned that I did pull the valve cover all the mechanical reasons for it to not run are sound the rebuild was done by an excellent machine shop here however I did visually verify the valve timing

Is the fuel pump coming on and has the correct fuel pressure? I need the fuel pressure before I can continue to help you-
