94 Honda Ex Will not start Where is the Fuel Pump Fuse?
When I purchased the car I changed thermostate . There is a wiring harness that connects to thermo - cover. Since then a bad ground has been a routine cause of failure to start. Well it s happen again after 6 months of reliabilty. I have been using a jumper wire to establish the ground. Last night it failed.Sometimes I hear fuel pump engage , sometimes I here the Fuel Relay Switch Vibrate, some times Nothing. This is consistent with past episodes.
Does anyone know which fuse is for the fuel pump?
Re: 94 Honda Ex Will not start Where is the Fuel Pump...
It is sometimes located on the engine bay or interior fuse box just check the labels.., or you can try turning your car on but dont start the engine try to check on the back portion or near the tank if you can hear the fuel pump. Failure or low pressure fuel pump will stall you engine.

You could have a short in the wire harness to the fuel pump or the fuel pump it self is bad or the relay has gone bad also. Start with the replacement of the fuel pump relay and also find the wire harness to the fuel pump sending unit from the frame to the gas tank and disconnect the connections. If the fuse does not blow when the connection to the fuel pump is disconnected, then it's a go chance that it's the fuel pump. If the fuse blows and the wire harness is disconnected, then the problem is towards the fuel pump relay and fuse block. Good luck and keep me posted, be glad to help you get your car running 100% again.
There may be a fuel pump fuse or connection you can undo but the relay is integrated with the entire injection system. If you disconnect it, you will lose spark as well. I would look through the fuse box first, I will drag out my wiring diagram in the morning and give you more specific details.
I have a 2000 Honda Passport. Once mine stalled, it would not restart. Sounded as if out of gas. I thought fuel pump. Took it to service station. They found a short in the electrical system. The fuse kept popping. They replaced blown fuse in coil and module. They tested misc wiring in main harness. They found and repaired bad wires in main harness for module and coils in left front inner fender. My check engine light was on for several months. Since I got it back from repair shop, it has finally gone off! I hope this helps! Good luck!
