thanks! It is looking like the pump however I've tested the electrics and thanks to haynes being unusuful as ever there is no wiring schematics for the fuel pump. On the pump there are 4 wires, 1 ground, 2 striped lives which both get 11 to 14v but a solid blue which gets no power or 0.02 it is this wire I need to eliminate first before I go down the route of buying the new pump. Has anyone any idea what the solid blue wire is for?

Thanks
