Recently did a auto to 5spd swap and the motor was running great @ 180psi all 4 cylinders until a couple of days ago I went to start the motor and the fuel pump didn't prime and isn't feeding fuel to the motor. A couple days later I go to turn on the motor I went and I replaced some fuses and the starter primed. Then today I went to start the motor again and nothing. I gave direct power to the fuel pump and it works fine so a bad fuel pump isn't the case. Checked the fuse for the fuel pump as well and replaced it, still not the case.

When I put it in ignition mode all power goes to everything but the fuel pump

Could it be a faulty relay, ECU issue, or a ground somewhere?
