The fuel pump will is fed +12 when cranking, after cranking the Flapper type
AFM has to be open which in turn closes a set of contacts within the AFM
thus enabling the Fuel pump via the 'Fuel pump relay'. Obviously a safety

All of this can be checked at the Diagnostic/ Check Engine Connector.
For a simple fuel pump operation, with the key in the ON position push the
AFM flap, you should hear the pump operating (quiet environment). Otherwise
check with a multimeter by probing the FP and ground on the diag connector.
We had missed the +12 to the Injector rails, in which case we resolved
within minutes of checking the Diagnostic connector - All you should need to
diag is here!!!
