At first attempt engine cranks and fires briefly. Then it might crank briefly and not fire. Then it won't crank. Leave it for ten minutes and it does the same. Starter solenoid can be hot wired and it cranks fine, but doesn't fire. I've got as far as the starter relay under the driver's seat and note that the earth wire (black/orange) rapidly goes open circuit, hence the no crank. Autodata and Vivid don't cover this Transit in gum boots, so can any one please help me with a wiring diagram. I am wary of hard wiring the earth, suspecting it is ecu controlled,
TIA,
Peter

Hi Pete,
I think you will find that the crank mode is controlled by a ECU and it is switched off after a pre-set time if it does not "see" the engine running.

How long does it crank for before it is switched off?

Hello Peter, I think this is an immobilizer fault, and even if this land rover has no key transponder or remote central locking all the hardware is there just dormant.
I have seen this fault before, if you phone me on Monday I will talk you through it.

Regards Martin.
