Car is a 94 GS with a B20B swap. suddenly the car would not start but cranked and got spark so i sent it to a small garage, my mechanic replaced the in-tank fuel pump but no results. He ran a direct lead to the pump from battery and the fuel pressure guage under hood read 22 pounds but needs 40 pounds. we do not have a wiring diagram and the swap was done a little half-assed with wires everywhere. do you guys have a good wiring diagram for the teg or any ideas what could be causing the pump to not create enough pressure (bad relays, fuses )?

you could have a bad relay causing a power drop and therefor not feeding a powerful enough signal to the fuel pump

there could also some sort of damage in the fuel line causing it to use pressure

or even a faulty ecu
