@jeep ride so it was your computer that ended up being the issue, not the Crank Position Sensor?

I was coming home from work engine just died had it towed to a garage near where I lived they replaced both cam and crank sensors still no spark they done a lot of chasing wire and testing parts they weren't sure the computer was bad so I towed it to another shop after more testing they finally replaced the computer been running every since that was eight years ago.

Re: 96 XJ Hesitation when hot & cant rev

SOLVED. Fuel Pump and pressure regulator were the culprits. Fuel pump would start to loose pressure after the vehicle was running for 30-45 minutes. 96 was the odd year that you can't find the complete fuel pump assembly for so I purchased the pump itself that used the stock connector. I cha get the small rubber line that goes in-between the pump and pump assembly along with the regulator and so far so good. It was easily missed as when the vehicle was missing and the fuel pressure gage was on, it still showed 51 psi. I only noticed it once I was trying to rev it up that the pressure would dip down to the 20's. All in, its a $890.00 jeep with the $500 purchase price included.

Good job.

Thank you for posting the solution and details about when the pressure dropped.
