It is in the OP's original description Rob, the car sometimes starts if bumped, so the cam sensor will be ok

He's changed the crank sensor, unnecessarily and the symptoms are right up there with injector leakback which is why Mike suggested it.

I have seen cars with excessive leakback start when "jumped" as the extra oomph supplied to the starter spins the engine that little bit faster

Leakback is also more evident when the engine is warm, as the fuel oil is less viscous and leaks more readily past the valving in the injector.
