    I dont think its the pins as i have tested wires before the pins so i think the problem is with 1 of the wires themselves. Thanks tho mate

    The 4 wires for the pump branch off the main loom at the back of the car this then plus into the small loom and bulb is wired into the wires that branch of msin loom just before the plug that plugs into small loom.

    Yes the bulb that was wired in to the loom was already there when i bought the car last year they had solder about an inch of wire to the posotive part of the bulb to he posotive wire in the main loom and the same for ground. Last week the car wouldnt start, i wasnt getting any fuel pressure so...

    The small bit of loom is fine, if i was to unplug at pump end and unplug where it plugs into main loom end i literally have the small lenght of loom in my hand. I unlplugged it from the pump and main loom end and left it on floor. I tested the plug which goes from the uec then plugs into one end...

    Also where your saying it could be corroded at the plug ive tested the wires before the plug (about 2inches) where the wires have slightly stripped from where who ever has solderd the bulb to the pos and ground wires

    Theres a length of 4 cables (around a meter long) that obv go into a plug at both ends, one end goes into pump and the other end plugs into the main loom. Its at the main loom end where the bulb is wired in and its the main loom plug ive been testing it with ignition on.

    The bulb is wired just before the plug tho. Which has obviously left exposed wires so if i was to probe the pins in the plug or the bare wires before the plug i still get 4v.

    Will try that when i can. Hopefully its just a case of rewiring the power wire. Will keep you updated.

    The pumps mainly, but i did try the chassis ground once. Just find it very strange how i get 13v with the bulb wired in.

    True. I did bridge the relay and got nothing. Bad ground Some where ? Or just bad posotive wire ?

    I was thinking about new wiring. But thought it could possibly be bad earth from ecu or a faulty ecu.

    And to add i was getting around 13v once bulb was wired in. Its a very strange one. Almost like its there to draw power to the pump

    Thanks Mark. There is no corrosion at the terminals you said also only get 4v at that connection. I wired a ba15s bulb into the pos and neg to the pump (this is where the old one was wired) which is pretty much next to the connecting plugs and presto the car started. But now the bulb has blown...
