    think mine is knackered. Making Lots of clicking noises. Checked earth and ok. Take it out, shake it and it sounds dead, lots of rattling.

    I assume it's fuel relay. I have two under he seat. One yellow, one black. This is the black one

    Typically, I need to be somewhere urgently. Can I replace it with the relay I bought for spots? They have the same pin outs

    Cheers

    Had to take the other car, boooo. What could the problem be?

    It did similar yesterday, but no clicking. Engine wouldn't turn over, sounded like no fuel getting to it (even though pump making a noise). I fiddled a bit with all fuses, checked inertia switch, bashed the fuel pump on tank with a screwdriver. It eventually started. But today no start at all, here is the video

    Ok, I think I cracked it (crossing fingers). After a lot of buggering about, checking fuel pump, relays, fuses, running new ECU earth, checking and cleaning all contacts, I think it was some melted cables. They come around the front of the engine block and would normally pass over/near/on the EGR pipe, but I removed mine a few weeks back. There are s few yellow cables which I think are for the injectors and a pink/brown that goes to a temp sensor on the front of the block, turbo side. I did the best I could separating, cleaning and insulating with tape for a temporary fix.

    Starts on the button now. I did test it by squishing them all back together - same problem as before so pretty sure it was that.

    What are the cables doing? Can I buy a replacement harness for that? It's really only the pink cables that are really bad with most insulation melted away.
