Another 2.7t - no start

[tsbpenguin]

2001 a6 2.7t 6mt, 170k miles. Got the car from a guy who had it parked for the last 5 years, but it was running when he parked it (he said only issue was he thought the cat was bad).

Changed all the fluids, and new battery, no start (not getting fuel). Put in a used fuel tank and brand new pump. Now it gets fuel and spark but no start. No engine codes on the VAG, registering rpms during cranking so can't be crank sensor. Haven't checked compression yet, but it sounds like it's getting compression.*

Clogged filter or injectors? Any ideas are appreciated.

If its been parked for 5 years compression is probably too low. Other possibility is bad gas.

id change out the fuel filter as well

Why would compression be too low from sitting in a garage? Can't be bad gas since we swapped out the old tank (with the gas in it) and replaced the fuel pump.

Yeah I'm going to do that next along with a compression test.
