ML320 no fuel pressure.
alright so my cats clogged and the car sat for around 8 months before i replaced them. in this time the battery died on me. i replaced the battery and now it just cranks and cranks. checked fuel pressure and its 0. i will say, before i let it sit, i checked fuel pressure and it was around 50's if i remember correctly. has new filter as well.
i swapped relays (k3) from another car, and still nothing. red light on dash still blinks, no error messages, no codes, all key functions work.
did my fuel pump just commit suicide during this 8 month sit or am i missing something? maybe AAM/DAS related?

How did you determine you have 0 fuel pressure? Did you put a gauge on the engine fuel rail?
Check fuel pump fuse,I see you've checked the relay...
Have someone put the key on and off and stick your head behind the rear back seat on the driver side. Sometimes it's hard to hear it run from the driver's seat. If you don't hear it then it's gone.
