2005 Jeep Grand Cherokee hot soak restart problem was created by Cheryl
Im having a fuel aeration issue I believe. Key on engine off fuel pressure gauge on schrader valve 58 psi. Then go to bleed fuel pressure off with gauge it has tons of air in it. I can fill up half a Mountain Dew 20 oz bottle key off. Bleed hose on fuel gauge submerged in fuel looks like your blowing in a straw in water. Checked fuel lines for missing heat shielding. Checked rail temp 189 degrees with infrared thermometer. Anyone see this issue before??

Heat soak produces fuel vapour rather than air I wonder if you have an issue on the suction side of the fuel pump

I installed clear hose between between fuel rail and engine feed line it didn’t look like it had air in it when running. But anything is possible
