+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 similarI 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.
