Got the same Problem on a 51 plate C5 HPI, starts and then after 1 or 2 sec's it cuts out. Suspect it's the ECU? Have had it tested by a local chap using diagnostic equipment but seems to through up random error codes which are unrelated. Looking to buy a new or second hand ECU? Can get it run in limp mode by taking off the sensor on the injection rail?
Anyone got any advice apart from scrap the thing?
