fuel pump issue, help please.
« on: 28 October 2012, 13:52:19 »
Hi folks, im having a bit of an issue with my MV6, X30XE. Its not pumping fuel when you turn on the ignition and still wont pump when I roll the engine. am I rightin saying that the fuel pump plug should two lives when ign is on or does it only have on until it rolls over to fire as mine has one live when the ign is swithed on( the fuel guage sensor) and the other three have nothing until its rolling over then the brown heavier brown wire becomes live. Is that wire supposed to be ign live or start live.

Just trying to work out if the fuel pump is knackered or I have awiring issue. ( I have replaced both the fuel pump releys)

Cheers.

Check for a spark at the plugs, could well be dodgy crank sensor

No stored codes, have a spark as it will splutter when fed carb cleaner straight into the throttle body. I dont know if the larger brown wire of the four that feeds the fuel pump is surposed to be permenently live with ignition or permenently live once the car has started. either way Ive got no fuel at all to the rail and the pump makes no noise (wherring type noise) at all.
