My car starts and runs for 10 to 2 seconds. Idle or stepping on the gas changes nothing. I have replaced the mass air flow sensor, fuel pump, fuel filter, battery, air filter, fuel, ignition, fuel pump relay. Any other suggestions or advice? I'm stumped.

This sounds like an issue with the idle air control valve.

Here is a guide that will help with this.

Below is the process from the manual that will help you replace this. If it were me I would do this and then retest the issue.

Let me know if you have questions. Thanks
