Default 02 wrx crank no start

So here goes, I have recently had my engine rebuilt(long block only) for my '02 wrx factory EJ205(which has been down for 6 months), searched all over the forums to see what I may or may not have done wrong.

Got the engine back and checked the timing, all matching up I tightened the cam gear bolts down to spec and one spun, so I re-did the timing myself. put the engine back together and plugged in the wiring harness. After all said and done I put the engine back in the car, connected everything that was removed and replaced the battery that died.

Attempted to start it after a week of installation and double checking everything.
All cables connected and engine grounds connected, even removed the intake and checked it all again. The car will crank forever but ignition will not happen,

pulled the #3 coil and put an old plug in and no sign of spark.
replaced the crank and cam sensors,
checked the ecu for damage(new ecu),
new walbro FP,
new plugs,
new oil pump,
new turbo(upgraded).

everything is connected the right way and installed to specs, have been racking my brain and checking everything under the sun to find and answer and no one on here has had the same issue as me. So if anyone on here has any idea or suggestion as to what I may have overlooked or neglected please let me know.

just curious as I seen on one post that a member stated all 4 coils failed after sitting for too long. is this possible?

Fuel pressure? Old Fuel?

Fuel is still clear, checked all timing marks. Its dead on, but my toner ring is missing a tooth that is right next to the sensor when all marks are lined up for the timing. I'm guessing that shall be my next item to replace. Would have thought that may just make it turn a few more times before ignition.

Multimeter tested the fuses,good. checked ohm levels on sensors, new ones went in as they zeroed out. I have no idea how to test the coils short of replacing them.

So I had a subaru specialist stop by and do a diagnosis and see what could be done. Found out I was losing fuel pressure at the #3 injector.

Changed out O-rings at all 4 to be safe. So I'm getting a few ignition pops here and there but not enough to get it to fire. Plus after several attempts at cranking it over and trying to get it to catch, I see smoke coming from under the manifold on the #2 & 4 bank.

It doesn't smell like burning metal or rubber from any harness wires, but my main ground cable is hot as hell.

Disconnected and removed battery, will update when I find the next issue.

Default Possible solution

A friend of mine with a Forester STI swap had a horrible misfire issue for a while. Turned out to be a corroded lead in the main harness. Stopped sending a signal to cylinder 3. I know its not totally on point with your problem, but I would ohm test the wires in the main harness and see if you have straight current flow through all of the wires.

Yeah I have just decided to send the car back to the shop that did the engine. Will probably find out what is going on with it here in a week or 2.

Update status:
Ecm was shorted out and did not have proper programming, crank gear missing tooth on ring, cam gear had a chipped tooth, and found a pinched piece of wire loom and wire under intake manifold.
Total cost plus towing $945.00. Somewhat better than I expected, but waiting to get the car back. Sux but I epically failed at trying to do it myself.

Well the tech fired it up while I was on the phone. It stayed running for about 3-5 seconds. He found the air leak from the pich plastic and wire.
Piece of advice always check and test the ECM before throwing parts at it.
