Ive finally hooked up my new battery to the car but i cant hear the fuel pump going when i turn the ignition to click 1.
if i bridge fp and B+ the pump runs without issue.
does it prime on ignition click 1? or does it only prime/run when the car starter is going?
to help matters ive removed an old alarm system, which wasnt actually working im told before the car was put in a field. so this may/may not be an issue.
trying to find wiring diagrams at the moment for it (JDM 93)
cheers

is there any fuel pump related wiring under the dash? drivers side? thats where most of the old alarm was wired in.

My fuel pump doesnt start until the dash lights are on (starter or engine doesnt need to be on) which i call click 2 (click 1 is stereo on, click 2 is fuel pump whirrs for a few seconds and heaters on and dash lit up and click 3 is the starter)
I suspect an old alarm/immobiliser would have cut into the fuel pump so maybe worth checking if the above isnt the case.

You sure it's your fuel pump whirring? PS pump will start and then stop once pressure is up, but the fuel pump doesn't until you start the car.

On the turn of my key I can hear the power steering pump wirr. Ok I guess I'll find out when Ive got fluids in her.

I see no fuel pressure until cranked.

thanks Jim, good to know

got the car started, appears as you said it does pump when being cranked.
