    Help hunting electrical gremlin

    Hey guys I could do with a hand, I have some electrical errors and could do with a hand fault finding...

    Could anyone of you guys measure voltage potential between black+blue wires and ground on n75 n80 or n249 valves in the engine bay? These are all common wiring so n75 is probably easiest to measure.

    Where is the j229 sai pump relay?

    Thanks...

    He had loads Jimmy, N75, N249, N205 open circuit, short to ground etc blah blah blah.

    I said they all had to be connected. Pete text me a while back, he had missed a blown fuse earlier in the week.

    All back streetworthy again.
