2000 A6 2.7l crank/no start

Hey all got a 2.7L Turbo that crank but no start. Car has been my project car for quite some time, had a bad overheat on original motor with 136k on it and found a crack in cylinder 1 that I believe the previous owner had filled. Anyway I bought a used motor with 42k on it, and dropped it in. but no dice just cranked forever.



I have been waiting for the snow to melt so I could work on it more, anyway here is a list of parts I have replaced over that last 2 yrs. Been replacing things As I get the money.



Fuel Pump- went 8 months after we bought car.

Fuel Filter

Aux Water Pump- Went 6 months after we bought

6 beru coil packs/ngk plugs

2 Icm's

rebuilt drivers side turbo- had a bad oil leak.

new starter

Ross-Tech cable/license

new crank sensor

2 new cps sensor

4 new coilovers- 3 had broken/cracked coils on them.

rebuilt Intake- all new vacuum lines



On Order arriving by next monday:

Head/cam/valve cover/intake/exhaust/egr gaskets full sets.

Head bolts

Egr- Combi Valve left side as brass nipple broke off.

Injector O-ring Set- cleaning fuel rail/injectors

other misc. items bolts, shouldered nuts etc.





I have been through the car and its driving me nuts. Checked Spark a zillion times- good. checked fuel injector Pulse-Good. Compression 160+ Good. Fuel is at the injectors, although I do have a question about them. If the car sat for long period of time with fuel/moisture could the injectors get clogged by buildup that way?



Any other suggestions? I have spent a lot of time and quite a bit of money rebuilding and im about at the end of the road as far as diagnosing the issue. timing is dead on the money as well that has been verified multiple times. right now it is cam bar locked, crank pin locked, as I removed the heads to replace gaskets and do some extra cleaning of everything.
