Thank you John/Horace for your response. The mileage is 48,000. Since the dealer was introducing "his gas" at he fuel rail and stating the problem went away, I mentioned that the problem would probably be from that point back to the tank. The dealer then suggested replacing the fuel pump ($1700.00), What if it checked ok? Received a message from FCA that they have closed the case. The car has one year remaining on the extended warrantee, which covers the fuel pump. So the dealer is afraid to replace a good fuel pump that will not fall under the warrantee. I didn't mention that if i drive the car and the engine has reached temp, then shut it off for about 5 minutes, no problem. I'm going to purchase a fuel pressure gauge and follow your procedure. I'll let you know the outcome. Happy New Year.
