new to rb20 swap, need help please

[eat_sleep_kingman]

S13 with rb20det swap. drove the car 3 days ago then stalled it before parking. got into the car today, it started then stalled like it ran out of gas. Fuel pump isnt priming so i hard wired it to a 12v power with 15amp fuse. The car is getting spark and fuel. pump works when i throw the switch, but the engine still seems to be bone dry on the plugs. I purchased a noid light tester to test the injector pluse tomorrow, i just thought maybe someone on here knew of something to make the fuel pump and injectors to not function properly

I forget but I think the ecu triggers the pump. So run that wire to your relay since you hard wired the fuel pump.
