1994 accord EX. Driving down the road and the car turned off. Couple minutes later it started back and ran for about ten minutes and shutdown, this time it wouldnt start back. Put ignition switch in and ran for ten seconds and shutdown. Put new fuel pump relay in and nothing. Put old fuel pump relay back in and started and ran fine. Turned it off and put old ignition switch in and fired right up and ran perfect for a week then shutdown. Pulled relay off and crossed over pins 1,3,7 to turn the fuel pump on and get power to the injectors, but still wouldnt run. Tried looking for ECU ground on thermostat, but theirs no wires running to it or anywhere around that location. Checked all fuses and crossed over CEL connector and light stays on all the time. Any help would be greatly appreciated.

 

The ground on the thermo housing is kind of a big wire. Don't expect it to be small cause it's not and it's covered in a black tapelike thing. It's easy to overlook.

Ignition switches seem to smell when they start to go, smell it. Those and main relays seem to be intermittent problems. Just replace them with new and call it a day.

 

I pulled the thermostat housing off and you can see where the bolt is supposed to be with the ground wires, but there not there. I bypassed the ignition switch and checked the really again and still nothing.

 

That happened to me all it was was that the o2 sensor was bad; idk if thats your case but its worth checking it out. the i took it to the shop and they made the check engine light turn off.

 

That wire has to be grounded for the engine to start. Ground it and see if it starts.

 

Checked o2 sensor and its good. I also grounded the ecu and still nothing. I guess I'm gonna go to the junk yard and get an ecu and try that.

 

went to the junkyard and got an ecu and that fixed it.

 

Nice ^
