Any thoughts would be greatly appreciated.

The specifications are all listed in the FSM on

You will hear the fuel pump running when you switch the ignition to the second but last position - it is then meant to stop until the ECU gets a signal from the crank sensor. This will happen when the start motor spins and when the engine is running.
The engine will not run with out fuel pressure from the electric pump.
If you are getting intermittent stalling (the engine runs most of the time) then it probably won't be the fuel pump.
"Deceleration stalling" is more likely to be due to the road speed sensor (if fitted) or the signal between the automatic transmission (if fitted) - if you have a manual gearbox then you need to post back for some other tips!
