Hi. I have a 1992 honda civic 1.5 liter.. I hit a bump in the road on the passenger side.. my car immediately cut off.. i crunk it back up and drove it about 7 miles.. it cut off a few more times that day.. i finally made it home.. the next day the fuel pump would not come on at all.. the only way the fuel pump would come on was if i jumped the relay.. bought a new relay.. fuel pump still wouldnt come on.. i took it to someone and they said they replaced the ecu...drove perfect on the way home... then started doing the same thing, which was losing fuel delivery and now its sitting in my yard and the fuel pump will not come on ... where do i start trying to find the problem? thanks

 

Did you check both dash fuse 24 and hood fuse 31? One may be blown.

If both fuses are good:

Unplug ECU connector A.

Turn key to ON(II).

Use a wire to ground pin A7 or A8 in the unplugged connector to the metal frame under the dash.

Does the fuel pump run as long as the A7 or A8 pin is grounded?

 

I had a problem with my '98 Civic cutting out while I was driving, but the problem was a worn out ignition switch.
