Hello. I have an 06 durango 4.7, lately when I go to start my truck it instantly dies (maybe one second) it takes a few tries but will eventually fire up and everything is normal and idels just fine. I can shut is off after is running and will fire back up. Usually only messes up after sitting for 8+ hours and sometimes it doesn't act up then. I hear the fuel pump kick on every time. So far I have replaced the battery, fuel pump relay, starter relay and ignition switch all to no prevail. Does not throw up any warning codes. Haven't taken it in yet because it doesn't act up all the time.
