Is there a chance that the fuel system could have become contaminated?

Try flushing the entire fuel system and swapping out the injectors for new ones.

I re-installed MY FPDM, WOT the car in park mode and it reached the 6000RPM till rev.

I drove the car and couldn't wait to reach an open road, took it up a small hill road and i was surprised! the car ran perfect with not a single fault!

Now what the hell was this headache for 2 month? What happened when i switched the FPDM knowing that yesterday i removed mine from the trunk and cleaned its connectors + its back. Did the used FPDM reset to the PCM or what?

Now shall i buy and ship a new FPDM? Shall i do something else to keep it running?

How do the connectors look? any corrosion? If there was an internal problem with your fpdm, then the used one should have worked.

So much bad diagnostic information here, it's incredible. A Throttle body problem because of a voltage drop to the pump? And no fuel pressure?? MAF problem because of the same issues? Replace this part, replace that part... Come on guys! Who has the money to just throw parts at a car hoping it will fix it??? lol.

I am very glad you figured it out, Tony_m. The connector probably wasn't seated properly or had a small amount of corrosion in it. Make sure to clean the connector and put some dielectric grease in there to keep it from happening again.
