I spent the whole day trying to figure out why the civic will not start. Turns out that the fuel pump is not getting any power. When I turn the key to on I do not hear it prime. I even swapped out the fuel pump with a new one and still no change. I open the fuel line to see if the fuel would spray but it didnt. I did change the main reply and that didnt help.

I did a test on the wires and found that one wire had a break in it. My question is before I go and cut and extend that wire with a new one, is there anything else that I might of over look?? Any info is apprecaited. thanks in advance.

 

Check ALL of your grounds, and clean them.
Same thing happend to me, but a friend figured it out before I bought a new pump thank god.

 

all the grounds are good.

 

The ECU ground on the thermostat housing is the main one that needs to be clean. Also do not paint the surface the housing mounts to on the block.

Cost me $200.00 to learn that lesson

 

Problem fixed. Wire at the switch had a break. thanks for all input.
