Peezen

Hi there everyone. This is my first post after doing a lot of research and trying everything I can to get this car started.

I have a 2003 Audi A4 B6 1.8T. I bought it as a project from a lady who drove until it died. I replaced the head because it had valves that had bashed a few holes in the underside of it after the water pump apparently failed and seized. The head is the same stamped head as the destroyed one, and the valves are good as far as I can tell.

It has a new timing belt and all of the associated gaskets, and the timing seems to be correct. Once getting everything back together I cannot get the car to start. It turns over, the starter sounds nice and strong, it just can't seem to catch and start. There are no codes for the engine when scanned on VCDS.

Here are some details of my process:

1. There are no engine codes at all but I will post a full VCDS scan below
2. I have a new battery installed
3. The ECU box had a couple of inches of water in it so I replaced all three submerged relays, including 219, 373, 395, harness seems ok.
4. I replaced the coolant temperature sensor
5. I swapped the cam position sensor with a few spares = no change
6. I tested the fuse #28 and have voltage when cranking the engine.
7. I removed the spark plugs and coils and cranked the engine and saw spark from each plug
8. the cylinders smelled of fuel, and the plugs were wet when removed, but I tested the fuel pump and it seems to work.
9. Fuel pump was noisy during output tests in VCDS so I replaced the Fuel filter which quieted things down = no change in regards to engine starting
10. fuel escapes from fuel rail when little access valve is depressed
11. All turbo hoses seem to be attached, no visible vacuum leaks
12. New air filter
13. No start with MAF plugged in or not
14. I ran a cold compression test (since I can't start the engine) and I got the following results: 1 - 70ps1, 2 - 40psi, 3 - 45psi, 4 - 70psi. Numbers seem super low and with large differences. Could the bottom end be the problem in the end?

I have lots of experience DIY'ing, and am active on the BMW 850i forum over at bimmerforums, but this situation has me stumped. I bought the car as a fun rebuild project but after all of the work I have put in I am close to just selling the darn thing as a non-working car

**EDIT** One thing I noticed was that the Engine label section of the engine scan is marked fail, could this be a problem?

Here is the VCDS scan:
