Car dies during start., Hmm possible problem? Options

[LeonStryfe]

Hey guys, I'm not exactly sure whats wrong, well I have an idea but I wanna hear your infos. When I start the car, the car fires but then the RPM doesn't pass 1k rpm and goes ot near zero to zero. The car vibrates for awhile (since the rpm is really low) then the engine just shuts off. The battery and light is still working. TI's just the engine suddenly just shuts off. Usually happens when Im starting the car. Spark Plug perhaps?

Any error codes being thrown? Dash lights?

Here are some thoughts:

To check the alt, hook up a voltage meter to the battery and start the car. If it jumps from 12 volts to 13/14vols, its likely fine.

If holding the gas pedal down keeps it running, then it could be the idle control vavle, which regulates the amount of air the engine takes in while idling. Clogged injectors or fuel filters usually strike at higher rpm first, unless you bought a really bad tank of gas that clogged everything up at once.

The ignitor issues I've seen in the past generally fall into the all or nothing category. Your driving fine one moment then the car dies and never starts again. But when this happens, you can crank the car until your battery dies - its doesn't stop the starter from engaging and rotating the engine.
