Engine starts but shuts off after 2 seconds. HELP PLPEASE!!!
Hey guys, my name is Ivan and I'm very new to the forum. I own a 2001 Monte Carlo SS w/ 119,000. I'm having a major issue where my car doesn't stay on right after starting, and a noticeable smell of gas follows.
Some concerns to note are:
Engine was misfiring prior to the issue. Changed the front three spark plugs about a month ago and that fixed the misfiring problem for about a week or so only. Haven't changed the rear bottom three yet because its almost impossible to change them myself, as you guys may already know how much of a hassle those three can be to change.
The last drive i had with it, the engine was accelerating on its own. Fluctuating idle and close to 3000 rpm when in park. Turned the car on after work that day and it just died after about a minute. Now it wont stay on at all. I give it a little gas and that keeps it going for about another 5 seconds but still dies when i let off.
Checked and cleaned the MAS and that seemed to be fine. Could it also be bad coil packs or ignition module? Clogged fuel filter? I've had a mechanic tell me it might be a bad fuel pump or bad fuel regulator, and I'm really really really hoping its not the fuel pump .
Any advise on what i should do next? Any advise helps!

There could be a quick fix to it, there is a Major Vacuum line the runs from the upper intake to the fire wall area on the drivers side if this is broken or off in either end it will cause the symptoms you are indicating. Any Vacuum leaks are an issue.
It could be the fuel filter as well that I would change anyway every 20K or so, if it hasn't been changed that you are aware of you may want to consider that, it should be located under the car on the passenger side near the rear of the front seat.
Another thing that can cause this problem is the Cat. Converter that could be plugged.
You might check those items.

Replace it and see if it'll fix your issue.
