so here is whats going on. just boosted my crx. put a 255 walbro in and heres the probem. started driving it and the car shut down. had it towed back to the garage and found out that my fuel pump was not turning on. finally got around it by jumping it but now the problem is i take the key out of the ignition the fuel pump shuts down but the car keeps running. anybody ever encounter anything like this?

 

Investigate the reason why the fuel pump isn't getting voltage through the stock wiring, there must be an issue with the main relay.

 

i replaced the main relay figuring that the pump wasnt getting powe because the relay was dead but still no power unless i jump it and put a kill switch to turn the car on and off

 

What do you mean you got around it by jumping it? Do you mean you jump start the car, or you're running a direct constant 12 volts to the pump?

Test the fuel pump power wire (yellow/black) with a digital voltmeter. Could be a short (bad wiring connection), blown fuel pump relay, or blown fuse.

 

Blown fuse, I forget which one but it doens't state fuel pump on it. #14 maybe? I can't remember, it was years ago. But a lot of people have one fuse blow after you install that fuel pump, then it never blows again. It's weird.

 

#14 fuse, alternator and solenoid valve.

 

thanks alot. hopefully this all works, otherwise i was gonna get a whole new interior harness because whoever had the car before me kind of hacked it up pretty good, i might still get a new one just because but thanks again

 

i am running a 12 volt source to it with a toggle switch to kill the car when im done driving it. but im tired of doing that so hopefully what the other guy said works
