On further investigation there is a fault in the wiring loom. The crank sensor is on a sub loom, following the wires back from that we find there is a short between the two wires in the main loom so it would appear that the ecu is not getting a pulse. Replacing those wires at the moment. This still doesn't answer the problem of the fuel pump not running. I don't recall seeing any labels on the loom, other than the ones that were put on to indicate where all the plugs went. I didn't get a wiring diagram with it, though my brother has bought a mondeo manual which appears to fit. Unfortunately I am at work in Wokingham and the car is in my brothers workshop in Tidmarsh.

If it's not then it's not happy. I can help but i need as many details as you can give me off the engine wiring loom and the adaptor loom you have. Did it come with any wiring diagram ?
