I have a 2004 Impala SS-Supercharged engine. As I was driving one night, the engine stalled and quit. I towed the car home and assumed the fuel pump was faulty. I replaced and the car started but ran only a few minutes and died. I replaced the fuel pressure regulator and filter. Fuel is present at the fuel rail/injectors. Still will not run. I disconnected a plug wire to check for fire; spark is present. With the wire disconnected, the car began to run again, rough idle, and died.
I pulled the diagnostic codes and they are: P0101 and P0452. Mil codes: Inc, Comp, and EGR.
Help!

This sounds like the crankshaft angle sensor or the fuel pump has gone out, when you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?
