Starting Issue: Need Help

The noid light flashes on all 8 while cranking and the car does not start. I will definitely do that check on the temp II sensor as it may need replacing as well. My suspicions on the injectors are rooted in the fact that the car was running fine until one day I procrastinated getting fuel even though I was SUPER empty. I went to class and came back out and she started, and then sputtered and died, then hasn't stayed on since. I have since then changed the fuel pump and filter, which was completely clogged and was dripped what looked like black soot. I think on that last pull of fuel, the injectors got hit with that black soot and clogged up. I'm going to send them to Witchhunter regardless, but I am also going to test my temp II sensor; I just didn't know how until now, lol.

Not to sound like a wise a** or anything,but are you sure you have enough fuel in the tank? It seems a little far fetched to think all 8 injectors are working and then plug up after a minute. You never know it may have leaked out or someone siphoned it without you knowing.
Also remove the gas cap before starting the engine and see if it runs any longer. The black soot you speak of that clogged your filter may be causing supply issues in the hose that feed the fuel pump from the bottom of the tank. If the filler cap isn't venting,you may be collapsing that hose after a short run.
Also get a can of carb cleaner and spray it into the air flow meter just after it stalls and see if you can keep it running on that. If so then you need to re-visit and confirm the fuel delivery system.
Does the car ever get to operating temperature?

Johnny, this clearly sounds like a mixture issue to me. Is there soot on your rear bumper above the exhaust tip? This would indicate a rich running condition.

There is more than enough fuel in the tank, I made sure of that one, lol. Also, there is no soot on the bumper and the exhaust tip itself is pretty clean actually. I should clarify that the car does indeed start when I leave it alone for a day or more, but it dies after about a minute and a half. After that initial start, it will no longer start up. Seems like it runs off the cold start injector and then dies when it tries to switch to the others..

Have you checked fuel pressure?

I did the test where you unplug the return line, put it into a container and jumper the fuel pump relay to stay on for 30 seconds. Tells you how much fuel was pumped up to the engine and returned to the tank. Should be around 1.3L in 30 seconds; mine was exactly 1.3L. This was after I installed a new fuel pump, fuel filter, and filter-to-pump fuel line.
