A cunning trick employed by our resident expert BrianMoooore is to wire a lamp across the fuel pump. Position the lamp where you can see it whilst driving, if the lamp stays on when the car plays up then you can eliminate the fuel pump wiring.

Dodgy immobiliser installed?
Dodgy ignition switch wiring?

Do as above, and more info on this 'clicking plug' required, including pics if possible.
