Car Starts Then Dies Immediately: Causes and Fixes

Quick Answer: A car that starts and immediately dies is almost always a fuel delivery problem, a bad idle air control valve, or a security system lockout. Check whether your theft light is flashing, that alone can kill the engine in seconds. If not, the most common causes are a failing fuel pump, clogged fuel filter, vacuum leak, or a faulty mass airflow sensor.

What To Do

Check the security/theft indicator light. If it’s flashing on the dash after the engine dies, your immobilizer triggered. Turn the key to “on” (not start) for 10 minutes until the light goes out, then try again. Some cars need a specific unlock sequence.
