More troubles for this blessed car.
At the shops this morning it would not fire, it turned over, but that was it. When it did start, the engine management light came on.

Could this be the crank angle sensor and if it is, how much is to replace, cause its a bugger to get to.

When you have trouble starting it again check to see if the tacho bounces. If it's turning over and not starting and it's bouncing it won't be the CKP. You might have a fuel delivery problem. It needs to be checked with a fuel pressure gauge and it should read around 50-55psi.
