So I know its been a while since the original post with this problem but finally got round to starting fixing things.
I desided the first thing to do was the crank sensor, since at least I would be able to start the car.
Having replaced it with the correct one, biggest hassel was finding the right cable, job its self it easy as. However, now the engine turns, which is an improvment on before but doesn't run. Initally I presumed this is cos I was jumping it with a metro so would be a lack of power, but having tried my mates 2.0 honda something the problem continues. The oil leak has left some oil sitting in the plug wells dispite my best efforts to clear them completly (intending to do this along with new plugs when changing the cam gaskets), would this effect the leads getting the spark to the plugs or is this going to be a fuel issue.
Basically I don't want to spend a few hundred on parts before knowing that the engine turns. so any advice on how to figure out what the issue is stopping the engine running would be a massive help and would be massivly appretiated.
