Urgent help required !!!
Last night My 8v gti digifant broke down.
The car will not run but it is firing ok, I think maybe a fuel pump problem?, i can't hear any noise from the pump when the ignition is on, i have checked the fuse which is ok can anyone help please???

now then matey. you have two pumps in a gti.one under the car and one in the fuel tank. have you checked both? you access the one in the tank in the boot through a black panal held in place with three screws.
You mention the car is firing ok but how sure are you? i have had a similar exsperiance. the sparks looked fine but they wernt! it turned out that the coil was knackered so try a new coil. they dont cost alot!
check your earth strap on the gear box to chassis. if you have a bad earth it will shag the ecu.
digifant can be a very sensitive system at times! (thats posh fo royal pain in the ass!)

Check that your fuel pump relay clicks when you turn the ignition. Also check for power at the fuel pump with a multimeter.

a mate had a problem like that. Turned out to be his ECU.

bought a fuel pump relay today, i hope thats all it is, will find out when i get home from work.
thanks for your help all, whereabouts is the ecu on the car? i hope its not that.

cheers
dave.

The fuel pump should prime the system when you switch the ignition on therefore you should here it run for 2 seconds before starting. If that's not the case then follow vr6's advice and check for power at the pump for that initial 2 seconds. If you're not getting power then it probably isn't your pump, check your relay and the electrical circuits surrounding it.

Let us know how you get on

I sussed it !!!!, some divy has run a wire from the back of the fuse box to the fuel tank sender.

Don't ask me why !!
