As you may have read. My 4x4 Cosworth has developed a problem. Last time I used it. It was spot on. Parked it up for a couple of weeks and now it won't start. It just turns over but wont fire. Strangely though it will start if you unplug the phase sensor?? I've tried different phase and crank sensors and still nothing. I'm suspecting either my new msd chip is dead or the ecu has gone tits up??
