sr20 sounds as if its running on 3 cylinders

[xpinoyxmk]

Need help.

Little background:

Went in for a car alignment last week, everything was good. Then yesterday I go to start the car and it sounds like a subaru, rev a couple times, very difficult to rev and it breaks up bad, and smoke coming out of the exhaust (heavy fuel smell). Caught me off guard, my assumption is that its running on 3 cylinders, so I go thru the regular procedure.

Spark, begin unplugging each connector to each coil pack, with #1 unplugged nothing changes, all others have a noticeable difference.

Fuel, same with pulling the connector. All have a slight but noticeable difference. Pulled the rail to see if the injectors are leaking or stuck open. They check out all good.

Checked for air/boost leaks, none.

Pulled the valve cover to see if anything was loose or a rocker arm fell off. Nope nothing.

Decided to test to see if anything changed if i pulled the fuel pump fuse. Normally it should die pretty fast... Nope, begins to idle normally except at 2000 rpms and stays running until i try to rev, then it will die. I assume its only running good because the excess fuel is burning off. Also longest i let it run, after pulling the fuel pump fuse, until I would rev it is about 30 sec.

Z32 mafs has been verified good. With it unplugged, there is no change for the better or worse. Also my tuner said the stock fpr's could be the issue.

If anyone has any information that could help, I'd greatly appreciate it.

Details on my car for reference:

180sx, original sr20, gtx2867r, hks 740cc, z32 mafs, enthalpy tune

Edit:
-swapped coil packs between #1 and #2, no change still on #1 unplugged
-replaced spark plugs with bkr7e's, gapped at .028, no change

Unsure if this is related but my fuel pump stopped priming/working for a short time.
