Cheers Pete yeah done that I've checked all the earths I could see I.e gearbox, bonnet etcpulled all the connections off and spray electrical connection cleaner on them all including ecu main connection and still nothing I'm completely puzzled now any advise on this as I'm stumped I have fuel to the rail here the pumps operating the hall sender works I have a spark this car should run, could it be ecu related?? Is it worth sticking the standard chip back in ?? Is there any thing I've missed??
It's just so strange that it was running ok I used a jump pack to fire it up but 2 miles down the road it just cuts out without no warning, no misfiring, no hesitation if was running fine!!!
Thanks for you help guys it's much appreciated
