I have a 1987 Honda accord and it out of the blue just stopped getting any power at all to go to the fuel pump. I have a repair book but can't find any answers. What should I look for to fix the problem? I know the pump isn't bad and there is just no juice going back to it

Try direct power from battery to fuel pump-pump turns on check and test fuse no.11, fuel pump relay and main relay.

We added a new fuel pump relay and it still doesn't work. Would anything get damaged if we direct connected it to the batery and drove the car like that?

How about the main relay did you check and test? If you can rig it with a toggle switch go for it-no its not gonna do anything wiring it direct.

Where is the main relay? Is it under the dash with the fuel pump relay?

Hi blitz210,

Fuel injected and carburetted models use different types of fuel pump relays.

The fuel pump relay for fuel injection model is incorporated into the main relay.

It is a seven pin dark grey or brown relay found underdash just above the driver side fuse box.

It is carburated and we replaced the fuel pump relay and have checked all of the fuses and still nothing. Would it be best to use a jumper wire and do a direct connect to make it work?

Thanks

Hi blitz210,

It requires a signal from the ignition coil, is the tachometer working?

Btw if it has an ECU under the passenger seat, then it might be causing the problem.

You can use a jumper to make it work direct, but in case of an emergency, the fuel pump would still be working if the engine is cut off with the ignition switch on.
