I have a 2004 Durango Hemi with 60k miles. Over the past year, it sometimes will not start. But most cases starts as usual. Repair shop couldn't find any problems. So I did a tune up - new plugs, coils. I even replaced the EGR valve and new battery. Everything seemed good until yesterday. Problem starting came back. Turn the key and nothing, but a few hours later started right up. No clicking while trying to start, instrument panel/radio lights up fine, no check engine light. No rough idle when running. So I'm ruling out starter or alternator issues. Any suggestions? It's not a constant problem, sporadic. Haven't had this problem in nearly eight months. Thanks.

 

The 2004 has many recalls. Call a dealer with your VIN to see if any apply to your vehicle.

Turns out the computer was storing a bunch of invalid key codes from my spare. Hope that did the trick.
