Could be a number of things first whip a plug out and check how strong of a spk you have. Could also be a bad earth which will cause a weak spark. Sounds like weak spark is the problem there are loads of things that could cause this but before I list them all check the spark first

Yeah should be a strong blue colour have you changed the rota arm and if so did you clean the contact with a bit of sand paper and wd40? If plugs are wet it means it isn't burning the fuel so must be spark??

Should also add why did you change the ecu and how much was it? To check bad earth put a jump lead straight from batt to engine but make sure you do negative NOT possitive. Or use a multi meter and measure the voltage between batt and then positive side of batt and engine? Should be almost the same?

Go on the V8 and Range Rover sections and do a search for "won't start" or "ignition problem" I'm sure you'll get a lot of info. Good luck.
