I have a 2005 Durango and it just dies on me and when I shut it off it won’t start. It turns over but nothing else, Just started today. Please help. Starter? Crank sensor?

If the engine cranks over but doesn’t start there’s nothing wrong with the starter. It could be the crank sensor.

To find out, locate the crank sensor. With the engine cold start the engine and let it idle. Take a heat gun or hair drier and point at the crank sensor. If the engine shuts off replace the crank sensor.
