I didn't mention the AMM as you were already pursing the fuel path. One thing at a time.

AMMs 'go bad' with numerous symptoms. And as jwalker noted--the big AMM killer is that they can get cooked.

The classic AMM Test, for a non starting engine, is to put it in the Limp-Home-Mode.
The LH system ECU has a Default Mode.
To put the ECU into the Default Mode:

******** Engine OFF. and as Art says: KEY-IN_POCKET
**Disconnect the harness plug on the AMM
**Then try to start the engine--if it runs, suspect a bad (or Cooked) AMM.

Thoughtful Bosch engineers.
So if the AMM fails, you can still get the car started and drive/limp it home.
