ISSUE SOLVED - SOLUTION POSTED

Hello.


Searched this issue, could not find a valid answer. You may take your flamethrowers out.

What happened: yesterday, my car was working all fine and had it's usual issues, but was running and starting. I installed new OCC and new air filter so it was running really nice. I went to my friends house, shut the car off, started it again to show how it was running. After a good minute, the car just shut itself off. Fuel pump won't prime, reset the fuse and battery, started up all good and nice. Then I and my friend decided to put on my new exhaust on the car, sounded nice, scraped, and had to take it off. Well, I was driving home and the car just shut right off when I let it idle at a red light . Pushed the car to the side, reset the fuse and the battery again, after few times off doing that it finally started up and I drove away... *drumroll*200 feet and it happened again (not sure if in gear or neutral, I just don't think about shifting). And at that right moment a cop pulls over behind me. My cojones went up into my body... After resetting the battery, and talking to the cop for few minutes, I decided to try starting the car again. I told the cop if it starts up, I am gonna drive away. So surprisingly, the cunt finally decided to start up and drive me all the way back home. I parked the car, and decided to try to start it up. NOPE. Wouldn't start and hasn't started since. It cranks until the battery craps out, but doesn't seem to be firing. In the video posted below, it tried to catch up once, but failed.

1991 240sx SE hatch.
SR20DET Redtop
Apexi head gasket.
Tomei Expreme exhaust crackafold (welding it soon).
Still has a cat.
Godspeed T25.
eBay BOV (venting to atmosphere, recirculating soon.)
GReddy OCC (hose going from crankcase to the T, from T to the OCC, and another hose from OCC recirculated to intake).
Vatozone "Spectre" air filter.
Battery relocated in the back.
All the fluids are perfect. Radiator topped off, oil is good. Never ran on empty gas tank.
There is fuel in the lines and I can hear fuel pump priming.
Wiring harness: f*cked beyond belief, would paste pics, but that's just too cruel to see. Getting a new harness as soon as I get the car running and take it to the shop.

Today, I installed a new Durablast fuel filter from '90-'96 300ZX TT. Cleaned up battery terminals, redid the wires, tightened everything how it's supposed to be.
My friend said my timing might be off by a bit, but it has been this way and the car was still going, didn't have time to adjust it.
Spark plugs are only 2 months old, but I already have another set. Will put the new spark plugs in Tuesday while redoing timing.
I will borrow my friends ignitor chip and his coilpacks to rule these out, but it won't be until Tuesday ;( .
What could cause this? Could the cylinders be flooded? I tried pumping the gas, holding the pedal down, nothing. Bad alternator? Never got a battery light on the dash. Tried starting the car without MAF, nothing. I will later on try starting it with fuel injectors unplugged in case it's flooded.
