04 audi d3 4.2L slow crank no start.

Hello. I've been trying to revive my d3 for months now to no avail as I've swapped multiple batteries (h9 Agm diehard) ,alternator ( which screeched upon advanced auto testing), starter,both relays in regards to starter in passenger foot well and fuel pumps Delphi ( brand new). I haven't had anything as much as one clean start since the car had a valve cover leak that I repaired last year. The engine is not seized or anything. My vehicle has 150k on the clock and is still very much valuable to me. I run obdeleven ( newgen) and the only code I get is for a motor mount on the passenger sidewhich is currently out since changing the starter. At first I thought it was a issue with conductivity/ continuity being disrupted by the slight corrosion on the braided solenoid wire but I have since then cleaned them uo with brasso and abrasion. I'm desperate to get this thing running as I've made buku money out of this vehicle and the other 2 cars I previously owned are now gone ( 2009 acura tl, 2005 saab 9-2x both black).

Seems like you are saying the issue started after you repaired the valve cover leak. If that is the case then you should probably focus more on whatever you removed to do that. If you attach a booster pack, does it crank faster? Have you examined the plugs and does the car have fuel in the rail (silly I know)? You have changed out a lot of parts and are assuming that all those parts are functioning 100% correctly and they may not be.
