Been fighting what seems like minor problems on our 2006 Jeep, and it's extremely frustrating. It's in great shape and really clean. Jeep only has about 70k miles on it, but it sat for several years prior to us buying it.
Since we've owned it, it seems like after an hour plus drive, it runs out of fuel. Around town, and up to that hour driving, it runs great. It happened yesterday. I could get it to start, but any attempt to accelerate was unsuccessful. I left to grab my scanner and went back to get it about 2 hours later. When I got there, it started and ran fine. I did notice there was some pressure in the tank when I removed the gas cap.
We've had (2) EVAP codes since we've had it, and both are "circuit" issue codes. P0443 and P0499. I've tested resistance and from what I can tell the wiring is all intact. I've also pulled the purge valve and manually actuated it with an outside 12v source. It opened as it should. The P0443 will clear with a cheap scanner, but the P0499 will not. My thought was to maybe drop the fuel tank and pull the EVAP canister to make sure all of the lines were in good shape.
PCM was replaced a couple months ago too. I really hope it's not the PCM as they are hard to find and no one really seems to have good reviews. I had a local shop replace it.
I did check fuel pressure and it's dead nuts at 58 psi which is exactly what the manual calls for... I let it run with the AC on this evening for a good 20-30 minutes and no fluctuation.
