Hey guys, I have a 1998 Civic DX Hatchback with a b20b swap in it, running on a p75 ecu. When I go to start the car, with the key in the "on" position, I don't hear the fuel pump turn on. I just replaced the main relay, all of the fuses are good. Recently did a new alternator and battery as well. Any ideas would be helpful. I've tried pretty much everything the other forum pages had to offer.

 

HAVE YOU CHECKED IF THE PUMP IS GETTING POWER WHEN THE KEY IS ON ..DO YOU HEAR THE MAIN RELAY CLICK ???

 

Does the check engine light turn off?

If the check engine light stays on, check for power to the ecu.

If you get power to the ecu, most likely the power regulation circuit in the ecu failed. Which is repairable by some soldering and a somewhat cheap integrated circuit and/or capacitors.

If the check engine light turns off, check the power wiring to the fuel pump.
