ugh, not quite i guess.

went out to start it again to let it warm up for a while. turned it over, fired fine. then accidentally tapped the throttle, stalled. and now my fuel pump isn't working again. (it'll make a whirring noise when in acc) replaced all fuses that i did before again, still nothing.

could i have flooded it and could there be a sensor that won't let the pump work until it's cleared?

Check your AFM flapper is not stuck in the fully closed position. It has
to move when you are cranking, to open a switch. That switch turns the
fuel pump on. With the ignition on, your should hear the pump start if
you poke the flapper with your finger.

Nope... no factory airbox, no AFM and no flapper !!!

Maybe the fuel pump is switched by the Circuit Opening Relay, just as
it was with the original GTS engine ? But I don't know what ECU you
are running or how your car is wired. If it worked last year, and you
have actually had it running, it is just a case of back tracking the fuel
pump power circuit until you find a loose connection, short or broken
wire.

yeah it was running after i changed all the fuses. and stopped working a few starts after. it's running a blacktop ECU on a 1st gen silvertop. you can hear the fuel pump prime in acc when its working and it stopped priming after a few starts. so i think i'm just gonna take a volt meter to the connection to the fuel pump. if there's power, then its the pump. if not, then its the wiring.

btw, the open circuit relay is bypassed. i tested for voltage at the pump harness and it reads 12v strong so i guess i need a new fuel pump.

so....it wasnt the pump. one of the ground broke off the assembly. so i rewired everything. tested it with the pump in the tank. worked. put the tank back on. put gas back in it, doesnt work anymore.

So it was a combination of ground, fuses and fuel pump?
