This one has me stumped 3/95 Jeep Grand Cherokee 5.2L See it’s right up your alley. Runs for 4-6 mins and dies. I’m posting a pic of everything that another mechanic replaced already before it came to me. Fuel pressure stays high even on stall out. Keeps spark after it dies. Trying to pull flash codes it starts to list them and then the check engine light constant flashes and goes away. I could really use some input on where to go from here.
