Help! 951 not starting

[Yan]

Hi!

Before writing about my problem, I want to let you know that my english is pretty bad. About a year after I ordered the 951, a problem that looked like an overboost protection began to occur. It was like hitting a bricks wall in 3rd-4th-5th gear especially at full boost but also sometimes at higher RPMS. The strange things:
- Often, the car stalled when stopping at a redlight or a stop after one or more overboost protections. It was running fine at speed, but as soon as I stopped I just couldn't give any throttle because it stalled.
- After stalling, I could start it back and everything was solved (it didn't stall anymore and often the overboost protection occured less easily).
- The problem began to occur right after I had solved a DME relay problem (the car often stalled in any condition). Changing the fuel filter and the DME relay solved the stalling problem, but then the overboost protection problems started.

I ran the car almost a year with the "what looked like an overboost problem", but about two weeks ago the car totally died! I don't know if it has anything to do with the overboosts/stalling problems. I parked it in the driveway and the car runned really fine. When trying to start it two days later, the engine cranked but the car didn't start.

Here's what I checked:
- I changed my DME relay again
- I checked all the voltages across the pins on the DME and everything is ok
- I can hear the fuel pump turning and the fuel rail working when bypassing the corresponding pins on the DME relay.
- I have voltage supplied to the injectors.
- I unplugged one of the injectors to test the FPR and the car didn't start

What do I need to check next, considering the provided details?

Thanks alot, and sorry again for my bad english.
CyaO,
Yan

Ho and one more detail: even if I hear the fuel pump turning when bypassing the DME pins, I don't hear it pressurize the system when turning the ignition on for the first second!
