Crank sensor?
this is annoying but good....cambelts ok, checked plugs and they are ok, checked injectors and they are ok. started it up to see what else it might be.....
AND IT STARTED FIRST TIME!!!!! ARRRRGGHHH lol
cost =£0.
annoying as he couldn't find anything wrong....worry is it might happen again....
or the immobiliser...
I think if it was the immobiliser then it wouldn't of let him turn the key to position 3 and it wouldn't crank over at all, he would be stuck on position 2 - the same as when for instance you insert the wrong Ford key into your ignition.
Also, get your battery checked as well as it's possible that it may be on it's way out.
