fuel pump timing control valve

[gerry mann]

anyone have a wiring diagram for a efi fuel pump timing control valve circuit
on a 2lte engine. keeps showing a fault changed pump 3 times changed ecd relays and checked fuses in both boxes but have i missed something

Gerry, I think I;ve got the same problem, does yours go into a limp type mode after 20mins running and brings up a fault 12? I will keep you posted if I have any success in sorting it.

Surely someone knows what code 12 means in the real world? Theres 3 of us now with a code 12! ???

[da SLUG man]

i think it means tea break... code 9 is definately a fight and code 10 is stopping boy racers.

Just a thought but dont you have to unplug the ECU for a minute or so to reset it or have you done that?
BTW the problem I had where the turbo stopped and the red check light came up has not happened again,,,, yet, (5 journeys to and from work - only about 15 miles each way atm) could it have been dodgy fuel?
(ed. I removed the fuse to the EFI for 30 secs. and it has cleared the fault code, the car is driving ok again for now but i'd still like to know what causes a code 12)
