Default Yikes…2y/o gas…get it out of the tank. Get fresh gas.

although when I charge the FP manually is does work and gas does come out of the line, I just don't get any gas when I crank it. That being said the gas has been sitting in the tank for the past 2 years, I'll give your advice a try and see what happens. The relay is ok, the fp fuse is ok, and the fp itself is functional as well, at this point I'm thinking maybe I should change the sparks as well, what do u think? but than again what would be the relation between sparks and fuel supply, even if the sparks are finished I should at leased smell the gas while I'm cranking it.
Whatever the stuff is in the bottom of your tank it has separated fuel/ethanol.

Really!? you would think so?
should I just drain it and refuel?
I did not know that could happen to fuel by sitting untouched?

The car was running fine until the tensioner shoe broke, I replaced it and now cannot get to start ...

Don't go looking for a lot of gremlins. Bet it is one simple thing like bad gas, or pugged injectors.

It must be because I did everything right and double checked everything, I just have to make sure the valves are not bent first, I just hope the valves are not bent.

Anyone have any tricks to verify if the valves are in good condition or not without buying a leak down tester?

Do you think if I manually charge the FP and loosen the gas line where the gas line is connected to the engine in order to clear the lines for few minutes I would risk burning the FP?
Does the FP initiate only at start up or does it work all the time while the car is running?

I think it would be hard to burn out the FP as long as you don't let it run empty for very long.

I don't know how/when the FP is switched on.

I left this back in Feb with expectation of bent valves on Bank 1, due to cam timing chain jumping multiple teeth when tensioner shoe broke. Clues were:
1. apparent angular misalignment of intake & exhaust cams in pics
2. interference when manually trying to turn crank before realigning cams
3. no compression in B1 was diagnosed by the Audi tech

Multiple cranking of engine since then probably not helping the situation.
Resetting timing won't fix bent valves. Checking fuel pump won't fix bent valves.
Seems like you're avoiding checking the most likely problem.

not at all, you are right! and as I mentioned the valves must be checked first before looking at any other different options and remedies.
