Next step is to check for power and ground at the engine ecu. What diag are you using?
Will check the model but it’s an icarsoft, it’s my mates he has it for his discovery… I’m pretty sure there’s power at the ÉCU, it’s turning something on in the engine when you turn the ignition on, a whirring noise which lasts for about 20/30 seconds (my mate told me that’s something that the ECU controls) … but worth double checking I suppose.

Hey all, this is where I’m at… currently we’ve tested the lives on the ECu and cleaned the earthing around the engine. We’ve tested the wires from the ÉCU to the injectors and we seem to be getting power to the injectors, the fuel pumps are also working. I’m stumped, maybe I’m missing something? Still won’t start
 
Hmm, so we could do with finding out which pin on the obd plug connects to to the engine ecu🤔 a more specific diag is definitely needed. Even with a specific diag it's not going to give a result if it can't talk to the ecu🤯

Yes, welcome to my hell, haha,. I was thinking to pay a mechanic to come over with a more professional reader… but would that help?

there is no pin labelled OBD or similar
re. connecting a nanocom -
Please note that in the Nanocom Evolution the software looks to the presence of the Body
Control ECU to know whether connected to a Discovery II or a P38 model. Unless you have
the unlock code for the relevant Body Control module the system will report a verification
failed message.

sorry, found it!! Connector 4, pin 32 Diagnostic K-Line

pin 36 is CAN high, 37 CAN low

Hi mate, thanks for the this, Sorry to be so stupid, but it’s connector 4 on the OBD, and then pin 32 on the ECU?

pin 32 on connector 4 of the ecu

to expand, pin 7 and 15 are labelled as EMS/ Engine ecu;
Light Green/Red - Main diagnostic line to BECM, HEVAC, ABS ECU, Engine ECU, Autobox ECU
Pink/Red - Main diagnostic line to BECM, HEVAC, ABS ECU, Engine ECU, Autobox ECU
