ok, I have changed the phase sensor. The car starts but cuts out after about 5 minutes at idle.

I have a group A coil fitted.

I have changed the ignition sensor. Changed the phase sensor. Put a new dizzy cap and rotor arm on.

A mate said there is a sensor on the crank that controls the spark, he said it could be that.

Any ideas where I go from here?

Or how to check if it's this crank sensor.

Cheers everone.
