3. Crankshaft position sensor fault (if the pump doesn't run when cranking. It will still run at "ignition on").
4. Fuel filter canister separation (a favourite).
5. Camshaft position sensor fault (doubtful in view of your evidence).

Checking if and when the pump runs is a good place to begin.

Thanks for the advice. I try these out when I get a moment.
