Recently picked up 95 Talon TSI as a project car. The car had a blown head gasket about 5-6 years ago (hasn't been registered since 2012) and hasn't run since. Previous owner took their time replacing the HG with her father, and after the HG was replaced it wouldn't start. They replaced lots of sensors, the engine wiring harness, ecu (then sent both ecus to ecmtuning and had capacitors replaced), removed the aftermarket alarm, and more. First thing i did was drain the old fuel and put new fuel in. The car is mostly stock aside from being bored .040 over, forged pistons, balance shafts deleted, and an ebay 16G turbo.
This thing will crank and fire, rev to about 1000-1500 and immediately die. It maintains fuel pressure (45 psi), spark, injector pulse, and rpm signal the entire time while it cranks, starts, revs and dies. Cam timing is dead on, I replaced the cam sensor on a hunch because it wasn't replaced before. I have tried both ECUs and get the same results. After it fires I can crank it forever and it will never fire again unless I unplug injectors, then its fire then rev then it runs out of fuel, then plug them back in and it'll fire and die and I can crank it till the battery dies. It will also fire and rev and die on starting fluid. It definitely seems and smells like it is getting overfueled. It has a stock ecu, stock injectors, plugs, wires, etc. I cant find a reason for it to be overfueling. Has OK compression, not great from my experience 120lbs (this is the lowest) should be enough to fire and run.
I am stumped on this thing so any thoughts would be greatly appreciated.
