Re: 84 accord no fuel feed
You need to put a test light on the fuel pump and make sure you are loosing power when this happens, it could be the main relay those are common im not sure if this year have a differant style as the newer cars but either way it could be failing you need to check the fuel pump relay when this happen also for power and ground if that is not the problem your ignition switch may be faulty try wiggleing it to recreate the promblem please rate -jeff

For a 1989 Honda Civic, to remove the fuel pump after you've removed the tank, disconnect the fuel lines and connector, then remove the fuel pump mounting nuts. If there's a ring, unscrew it to remove the fuel pump. ------------------------------------------------------------------------------ Digimaster 18
if you have someone try to start the car while you hit the gas tank in the centre of the fuel tank and it starts then the fuel pump is no good.note this doesn`t always work due to how bad the pump is seized.if you look for the fuel pump feed wire under the hood,its a green wire with a black plastic connector and with some one again trying to start the car and with a test light connected to the connector it should light up.if it does then the pump is no good.another way is to have someone listen at the fuel tank and feed power to this same wire if the pump is working then they should hear the pump run,they may have to listen at the filler neck with the gas cap off to see if they can hear it run.
If you have verified a no power condition by pulling the tank and measuring the power signal to the pump then either your fuel pump relay is bad, or you have a bad fuse, or a broken wire somewhere in between.
My guess is that the fuel pump no longer comes on when you turn the key to the on position and that you havent dropped the tank to inspect the pump yes? If this is so you may have a bad fuel pump as well. What I would do is check the fuses for the fuel pump and make sure they are not blown. Then I would check out the relay, visually inspect it, the top should come off of it, look for any burnt wire traces and components inside the relay, you may be surprised to find other relays in your car are the same as the fuel pump relay. Swap one of those out with the fuel pump relay and see if that fixes the problem, this will save you the money of buying a new relay before you know it is your problem. If the relay appears good then you may have to drop the tank and install a new pump. Some vehicles have harnesses under the hood which allow you to feed power directly to the fuel pump so you can test it to make sure it is good before you drop the tank. Some don't. You can feed power directly to the fuel pump by jumping the pins on the relay, I am not familiar with the pinout on your cars relay however and could not advise you which pins to jump to feed power directly to the pump. Get a chiltens or haynes manual, they should have wiring diagrams in them.
Then either the fuel pump has failed, fuel filter is clogged, fuel pump relay is bad, or the fuel pump fuse is blown. Sit in the car in a very quite area or with someone listening at the fuel fill area with the cap removed and turn on the ignition without starting the engine. The fuel pump should come on for a few seconds and then shut down. If it does not then check the fuse and the relay. If it comes on then you know the fuse and relay are good. Replace the fuel filter. If that does not help more than likely the fuel pump is bad and needs replacing. The pump can run and still not be pumping any fuel. A fuel pressure test will verify if the pump is for sure bad. You have an 11 year old vehicle so it would not be uncommon for the pump to go bad especially if the filter has been neglected. A partially clogged fuel filter will destroy an otherwise good fuel pump. You will have to remove the fuel tank in order to replace the fuel pump. Use a hand pump to remove as much fuel as possible from the tank as gasoline weighs around 8 lbs per gallon. The less weight the better. Good luck and Merry Christmas.
sounds like the fuel pump went out. It is located inside the tank. turn the key but dont start and have someone listen for a 1 to 2 second hum by the gas tank. If they hear nothing then your pump is bad. REplace your fuel filter first, it is outside the tank and could be clogged. YOu could get lucky, but I bet your pump is bad.
Jim; have you confirm the fuel pum[ is working? If it is, you should get something out of the fuel rail. Sadly. Pump is a dealer recommended repair cause the pump is more than likely in the fuel tank. Thry should changre you filter at the same time.
