Hello! I'm fairly new to the S chassis, and picked this one up a few months ago.
Everything was fine and she was running good for the few months I had her. changed fluids and all that basic maintenance stuff.

Last week I took her out my garage to clean the inside, started up fine.
Tried to start her back up a few hours later, Battery then died, replaced the battery, and now she does not want to run at all.

Cranks, sputters, sometimes idle to barely ~500-700rpms and dies.
Rarely it will go over 1k-2k rpms, and ill try giving it gas then, but dies immediately after trying to push the gas pedal down.

I checked TPS, running on 0.45 volts to 4.11 volts WOT
so that looks perfectly fine.

I replaced fuel filter and looked for vac leaks a bit.

Nothing so far.

I tried unplugging the MAF, no changes at all I believe.

What else can I hunt around for?

I asked an "expert" on SR20DET'S and all he said was my engine is "fucked" and that I need a full rebuild lol.

Thought I'd ask here before I take that route, Thank you.

Heres a google photo link to my engine, (cant figure how to upload on here)
