Hi all, my 2007 Jeep Grand Cherokee 3.7 L start and runs fine when it is cold. Once it gets warm, when I shut it off and let it sit for about 15 minutes it will not start, it just cranks and cranks. Does not happen all the time, only seems to happen when it has a full tank of fuel. I hear the fuel prime when I turn the ignition on, and there is pressurized fuel at the port on the passenger side of the fuel rail.
Also, no codes, or check engine light, and car runs fine once it starts.
Looking for some guidance, before I start throwing parts at it.
