    Ok, so I've changed the fuel pump relay, checked the fuse, changed the fule pump and.........IT STILL WON'T F**KING START!!!! :banghead:

    The pump still isn't priming. Could a blocked fuel filter/fpr cause this??? :think:

    No mate, it just turns over but won't fire up. The pump isn't making the whirring noise that you get when you switch the ignition on so I know it's not priming

    Going to do that in the morning Paul. I just assumed that seeing as the fuse and relay were ok, and, the pump had been whining it's nuts off that it was definitely the pump!! £115 and a lot of messing around in the dark with a half full fuel tank later and there was chuff all wrong with it

    Well, i have seen a faulty ECU cause this, as it's whats responsible for sending the signal to the relayto prime the pump. It also could the the cranksensor, as if the ECU isnt seeing a signal to run the pump, it won't

    Will the car run with 12v being fed direct to the pump?

    dodgy fuel pump relay? as what was said above.... is there a live/earth getting to the pump? does it run if you power it up?

    OK, so I plugged it in this morning and brought up numerous fault codes for abs, misfire from coil packs etc etc.............and NO SIGNAL FROM INSTRUMENT CLUSTER TO ECU!!!

    Cleared fault codes and bingo - it started! WTF was that all about? I have no idea what caused it either. Unfortunately, I now have a few more issues......please see new post entitled 'effin' pile of shi........'

    Have you checked the earths under the battery tray? not sure how tied into your exact prob it may be but to get so many electrical faults in one go is usually the result of wiring/earthing probs...
