Thanks Sean for the reply. It turns over fine and I drained the battery this morning tring to start it. I took it out and put it on charge for a few hours and at about 4 oclock today it started first time. MIL? if thats the heater light then yeah that works, it stays on for abour 20 seconds and then I turn it over when its very cold it takes a bit longer to fire though. A nanocom means main dealers for me I'm afraid. So it started no problem when it was 7 or 8 degrees warmer and a fresh charged battery, does this mean thats its hardly a sensor problem?
