I need some help regarding the fuel pump wiring mod. After changing my mates carpet on his 20vt last week the car now refuses to start. A quick look last night
And we've got no fuel pump. I started checking the usual ( inertia switch, relays and fuses) to find the pump has been directly wired from the battery, past the pump relay and along under the passenger side carpet. I'll be going over tonight with a multimeter to check continuity and voltages but I need to know whether that mod is intended to work in conjunction with the existing relays, fuses and inertia switch or bypass them completely.
