Success!!
had a look under the bonnet and couldnt see any frayed wires from the ecm, (probably because theyre in the plastic sleeve duuuh) so just double checked it was connected properly and gave the sleeve a little shake, replaced the fuse and bobs your uncle, we have lift off! thanks for the help, feeling satisfied with myself not having to take it to the garage for once! |

Check that engine harness carefully. They are notorious for chafing at any point where they touch the engine or are secured. If you're lucky, a fuse blows, but the main 100A feed from alternator to battery is in that harness and if that grounds your vehicle will spontaneously combust.

Looking at the posted wiring schematic - the designers of the engine management see fit to equip it with 2 power inputs - in case one fails. Land Rover then connect them together and to a common feed thereby undoing all that effort and creating a single point of failure.
DOH! |

It's because it's a Ford Transit Engine harness being grafted into an existing Defender TD5 body harness - and it was done on the cheap. |
