Does anyone have or know where I can find a wiring diagram for the fuel pump through to the immobiliser/ignition. Needs to be for a V5/V6 uk turbo.

Car won't start as fuel pump is not priming and we've tracked it down to possibly the immobiliser/alarm. We have worked out that from the connector in drivers footwell back to the pump works fine its just from there on its not working but no idea where all the wires go from there forward to control the fuel pump.

If anybody is good with electrics and fancies given me a hand to solve the problem they are more than welcome to help if your not too far from Porth.
