Default Car starts then immediately dies

Like title says, car literally starts, then dies...When it turns over if i floor it, it bubbles and stays on a bit but if I let the gas off it dies. I hear the pump prime but I know that doesnt mean its working. Once in a while before the car would like bog, if I lifted and got back on it, the car drove fine again. It was very intermittent.

JUST changed the filter thinking that was the problem but that wasn't it. Any takers?

Get a pressure test gauge on the fuel rail to check your fuel pressure. Your fuel pump could be shot.

could be something as simple as clogged fuel injectors. Mine was doing something similar. it would start up and immediatly stall, but then i could restart it and it'd be fine. I ran some fuel injector cleaner through it and it now starts and runs fine.

Ive seen icm's do that before. Infact mine did the same thing when it went out. It would let the car start for a quick second then die right away.

Id still get a guage on the fuel rail first though.
