    1989 3.5 V8 EFI question - fuel pump and sequence of fuel delivery

    I hadn't even considered that, it's a good point and I'll have to check

    I will check out the flap first, then pull the fuse, if that doesn't change anything I will get stuck in to the wiring and the ignition switch, Kev12 has also made a point "Worth checking a PO hasnt done a "mod" to the pump wiring?", something that I hadn't even considered.

    Thanks al-one-arm, I have posted what I have in the workshop manual, I desperately needed it in words of one syllable before I rip it apart, the more clarification I can get the less time I will need to spend remembering how to use the multi-meter!

    Thanks Ratae, Yes, I have flapper air flow meter & the 4CU ecu. when I turn the ignition switch to the first position nothing happens, when I turn it to the second position the pump kicks in but it never stops in that position, my impression is that it should stop once the system is pressurised...

    1989 3.5 V8 EFI question - fuel pump and sequence of fuel delivery

    Please can someone advise me on the sequence of fuel delivery, the fuel pump is running all the time before I start the engine and is really loud, sounds like an old bendix top loader washing machine! Looking around I think that it should come on when you turn the key to the second position...
