I left the battery unplugged for half hour and then it started again... something must of reset itself? would you replace the crank shaft sensor or do you think this could be something else causing all the problems?

I think cam pos sensor

need to take the cam position sensor off and clean it with some contact cleaner
have a look at the terminals and make sure both sides are clean and not rusty or going green
it may be mucky or it may well be knackered
