HELP HELP HELP!!!

Everyone, I have a sick '94 that needs help.

I was driving a while back and my engine started running poorly. I made it home by high revving the engine but it died immediately after getting in the garage (idle.)

Engine can start and run, barely, and seems to be running on only a few cylinders.

I've tried:
Replaced headgaskets no change
Replaced Timing sprockets/ chain (thought it may have skipped a tooth. It was sloppy, and glad I changed it) no change
Replaced: camshaft sensor 2X, crank sensor, MAP sensor, ignition coil packs, BOTH ECU and the PCM. no change
Drained tank, fresh gas. no change
Fuel pump and filter are fairly new. I can hear it pump up at key ON.
Ignition wires are good, (And, a bunch going bad at the same time shouldn't happen.)
I've got spark on all cylinders.
Checked a few injectors. Screens are clear and they seem to function properly.

I am completely stumped.

It starts, and I can rev it up.... but it's definitely not running on all cylinders. Feels, sounds like three. The passenger-side exhaust doesn't even heat up. Driver exhaust does.

NOTHING I've done has made any change whatsoever.

HELP!!!!

No OBDI codes?
Did you try the Cycling Key trick to read them?

Weird, It does *sound* like a fuel issue. Did you change the fuel pump? Have you put a gauge on the fuel rail(scharder valve) to see if you are at 55PSI?

Fuel injectors- I would still pull them all and get them cleaned a checked professionally. Maybe even install Gen 2 injectors(red tops) to have slightly better fuel flow.

Where are you located?

I live in Atlanta.

I have a code reader. I had one code for the MAP sensor at first. I changed that, as well.

I can only assume I have a wiring issue.

Anyone point me towards a pinout of PCM/ECU connectors?

Thanks to the responders!

I have a 92-96 PDF parts manual but i doubt it has pinouts..
Is the car stock?
