*The switch behind or on the end of the key barrel assembly, this though tends to be a start, stall, start stall type of fault.
*Failing crankshaft position sensor. from all I have done it doesnt throw a code, only use genuine (as in Ford part).
*Pinched fuel line between chassis and body just after fuel filter. Keep in mind often when a suction line gets a kink or pinch it will collapse more.
*as10 signal fault between it and ECU, this is often a break in the harness somewhere, also check for any water ingress into the as10 (as10 is the imobiliser).
*Other harness related breaks, short to grounds. the electrical harness in general tends to be too short and can get cut, plugs come part, pins back out of plugs.
*Front of top of engine main harness, follow it round the passenger side towards the firewall, about 300mm from firewall there is a plug, ensure its clean and no pins have backed out.
*3 plugs that connect to the ecu at the firewall, 1 especially the harness really is too short and stretches the wires, ensure they are clean.
*After that, numerous breaks in the harness and very random places.
Way way down after all that the IP cluster can fault, but this is rare.
a faulty ecu and again very rare.
