I have a 2002 Dodge Durango RT. When the engine is cool it starts with no problem. But once the engine is warmed up, it won't start. You have to wait 20 to 30 minutes for it to cool down before you can get it to start again. When it's warm it seems to have fuel pressure, and the starter turns over the engine fine. But you can crank and crank and crank and she will not start until you let her cool down. Any ideas?

 

See what's missing, spark, injector pulse, or both.....
