My dodge durango won't start after i drive it for a while. After looking around i've seen many people say that it won't start after it's been warm but will start when it cools and i believe this is the issue. I haven't gotten a definite answer on what to replace. I had to let the car sit for a while to replace the engine oil cooler . Once that part was replaced the car would start whenever i needed it to for a few days then went right back to not starting after being shut off. It takes well over 30 minutes before i can start it again. Everything else will work...the radio, lights, windows etc. Any ideas what could be going on with it?4

 

First off, welcome to the forum! Please provide a bit more definition of "won't start." Does the starter spin the engine over, just the engine doesn't fire and run? Or does the starter not even spin the engine over?

What tools do you have available to you to diagnose the issue? For example, do you have a fuel pressure tester, or a spark tester? How about a noid light set? Which engine does your 2014 Durango have, the V6 or the V8?

The first thing that came to mind was that your generic description of won't start when warm, but will after it cools is a failing fuel pump. But that would only be the case is the engine spins the engine, it just fails to fire and run. Without a fuel pressure gauge or noid light set, you could test this theory by spraying some throttle body cleaner or starting fluid into the intake at the throttle body or through a vacuum port and if the engine sputters like it wants to start, or it does start, then the issue is with the fuel system. If it still doesn't attempt to start, then you are probably looking at an ignition issue.
