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
-
Any stored codes?
-
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.

Have you checked both fuses, one in cabin the other by battery
-
tried the twenty in the fuse box, Didnt know about the one next to the battery tray, Which one is it?

Update; Fuel pump is trashed, recieved the new one today, vauxhall price £219.88 FSE unit from an online company, £65.20. guess which one I picked.....
fitting it this weekend and hope she'll fire! P.S the feed to the pump is working as it should :y
-
Should have posted a wanted ad on the forum.You could have had a known good one for £20 delivered. ;)

My school report used to say "must pay more attention" to :'( :'(
Any way, roll on the weekend and the sweet sound of a 3inch stainless singing my tune :D :D :D :D :D

FIXED, she is back firing on all cylinders and the old fuel pump flew into the bin at 100mph.
Im happy :y
