Question about 1987 Honda Accord

1 Answer

No fuel problem

I dont have current at the fuel pump. i've just replaced the main relay and i know the fuel pump works.i have current to all the fuses under the dash and under the hood. there is one fuse under the dash that says fuel pump-alternator and its good. the engine runs by spraying a little gas into the intake, so i know the engine runs.

    THANK YOU VERY MUCH FOR YOUR HELP. I GOT MY HONDA RUNNING. YOU MENTIONED THAT IT COULD BE A BAD GROUND, AND THAT GOT ME THINKING BECAUSE MANY TIMES I'VE HOOKED UP AN AMPLIFIER AND IT DIDN'T WORK BECAUSE I DIDN'T HAVE A GOOD GROUND. SO WHAT I DID WAS RUN A JUMPER WIRE FROM RIGHT OFF THE BATTERY NEGATIVE AND PUT THE OTHER END ON THE RELAY TERMINAL UNTIL I FOUND THE CORRECT ONE AND HEARD A CLICK.THE CAR FIRED RIGHT UP.NOW I'M NOT GOING TO GO THROUGH THE TROUBLE OF FINDING THE BREAK, I THINK I'M JUST GOING TO SECURE THAT JUMPER WIRE ON THE BATTERY AND INTO THE CORRECT TERMINAL IN THE RELAY. THANKS AGAIN OMMJOHN

    OK THATS A GOOD SIGN!!Now test for output voltage after the relay.Turn the ignition on you will only have two to three seconds before the relay shuts off current.if the relay clicks then your doing good.if you have voltage coming out of the relay then there is a break in the wire's somewhere.Possible bad ground.do a ohms test on your wire from the relay to the fuel pump.if you get no reading there is a break in your wire.

    did you check to see if you have current to the relay when you first turn on the ignition?

My 2005 l200 wont start but if you run a lead from battery to switch on pump it starts take lead of and it stops new switch on and still no start.


The fuel pump is powered from a relay. That relay is powered by the engine's computer ("ECU"). The relay is necessary to scale the low current control signal from the ECU into a high current switch to operate the fuel pump. The high current circuit will likely contain a fuse. That fuse or the fuel pump relay may be defective.

The fuel pump relay is activated for a few seconds when the ignition is turned on before starting the engine. If everything is working properly, you should be able to hear the fuel pump run for those few seconds before starting the engine. This is so the injectors have adequate fuel pressure before the engine is started.

Dont know which fuse operates fuel pump


) Unplug the main relay and then turn the key from off to ON(II).

2) Use a jumper wire or paperclip to jump terminal 1 to terminal 7 in the main relay plug. Does the fuel pump run?

3) Now use the jumper wire or paperclip to jump terminal 5 to terminal 7 in the main relay plug. Does the fuel pump run?

My car just stopped working it seems no gas is gettin to the engine but it used to stall alot not like oh s*** im out of gas but the stall when you press the gas and absolutely nothin happens then the car...


Here's a technique that works for me. Locate the fuel pump relay, in the fuse and relay panel. Pull the fuel pump relay and look at the bottom of the relay. You will see that the cover can be removed by carefully prying it off using a small flat blade screwdriver or an x-acto knife. Once the cover is removed, reinstall the relay. Have someone start the car while you watch the contacts on the relay. If the contacts close, the relay is OK. If you turn the key to on without starting the car, you car close the relay manually. (You can use your finger to close the relay. Listen carefully, at the fill tube with the gas cap removed. If the fuel pump is getting power you will hear the whine of the motor. If not then check the fuel pump fuse first then the 12 volts at the connector on top of the fuel tank. I've had a problem such as you described, where the car will start but stalls if you try to give it gas. I found that some GM's use a small (2 inch)section of rubber hose to connect the pump to the steel fuel line inside the tank. The hose splits which allows enough fuel to reach the engine, but not enough to run it under any load. The fuel filter should be replaced if it is suspect, but probably isn't your main problem. Hope this helps! Dano

2002 intrepid 2.7 Im getting no crank from the starter and I dont hear the fuel pump kicking on when the ignition key is turned on, I do get power to the radio and dash, Ive checked fuses and replaced...


Under the hood, there should be a fuse block. Remove the cover and there will be a 20amp(i think) fuse that protects the fuel pump and starter circuit. I've run into this problem many times and every time it ends up being the starter that blows the fuse.

Fuel pump does not come on


Check the fuse but there is a good chance your fuel pump needs to be replaced. If the fuse is good check for power to the pump first then you will know you need a pump

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.
