Right during a break in the weather I managed to get outside and get pulling hoses off.
I took the main fuel feed hose off inside the engine bay and there was plenty of residual fuel left in the hose.  I wrapped an empty crisp packet around it and used electrical tape to keep it on there and cranked the engine a fair few times.  No fuel appeared to come out so I took off the crisp packet and tried again.  Absolutely no fuel coming out so I\'m hoping I have found my culprit.

in the black diagnostics port in the engine bay bridge the FP and ground pins together....this will manually activate pump....you should here a gushing sound....also check fuel pump fuse and resister under brake servo...you can also direct live the pump to eliminate wiring issues...if your pump does not work direct from a battery then your pump is goosed...
Definately want it mate but the dog has just died so will be getting the missus a new dog for christmas....
Sounds like a good deal but will have to ask the dragon first.....  :flamed  :spank

Well I\'ve got current going to the pump but I have no idea which pins in the diagnostic port to ground together.  Anyone got a pic so I can try it tonight or tomorrow?

There is a diagram on the underside of the cover, jump F/P and GND, then turn the ignition. Oh, pop the hoses back on first or you\'ll spray fuel everywhere if it\'s working.

Would be very interested to hear the outcome of this issue. I have the same problem at the moment. When I get a chance this weekend I\'ll try bridging the pins in the diagnostic block and see what happens. I\'mm 90% sure there is something up with the fuel pump as I can\'t hear it humming any longer.

I\'ve got a standard fuel pump if either of you need one, give me a shout

Cool, if I find out it\'s the pump 100% then I\'ll drop you a PM as I\'ll be interested in a replacement. Not had a chance this weekend, but will do a quick test over lunch and see what I can see. Cheers.

Ok, still having issues with the fuel pump running, to save typing up everything I\'ve tried have a quick read of my initial post here.

I\'m really not sure what to try next, something in the ignition wiring that I\'m missing? All the voltages on the fuel pump relay in the engine bay seem to be correct also.

Thoughts?
