I am nowhere near being an expert but from what I have read on here you need to check the readings from the cps when starting.

+1^^^ and a fuel pressure gauge connected to watch the pressure while cranking cos on defenders i've seen many cases when this kind of stubborn starting issue is fuel supply related hence no fault codes albeit a nanocom or haweye is compulsory to rule out a quite common topside switch failure in the ECU which is not recognised by other generic scantools and the symptom is similar

Thank you for your replies - Ive looked through the videos and to be honest I havent considered a fuse being part of the issue.

I plugged in my pscan this afternoon and ive attached the readings - I just crank her over and then took the readings (Ive ordered a nanocom - i figured its about time I did!)

Whilst landy is my wife's daily driver (she is retired and its for the dogs etc), we have another car so Im trying my best not to overthink this. That being said this issue is taking all of my braincells.

I'm not sure that the scanner you used is reliable but if it is i see that the fuel pump drive is off so you can't expect it to start that way, the pump should be on for about 3 minutes after the ignition was turned on then if the ECU doesnt get a rpm signal it turns it off
