Problem happened a couple days ago and have been trying to fix it. Car is a 1991 318is with an us s50 swap and it won't start, I never heard the fuel pump when I tried to start it so I figured that was the problem, I replaced it with a tre fuel pump and I know I made good solder connections to the pump assembly and it is wired and installed correctly, however I do not hear it priming and it is not getting power and car still has no fuel, I do not know which of these relays is the fuel pump relay and if someone could help, I bought it a week ago and would love to enjoy it some more.
