My 96 2.5 XJ sat in a pasture for about five years. The fuel became a solid, but fortunately there wasn't much left at that point. I ran a 90 model sending unit for a while until I was able to repair the original with a new pump. I put a Carter pump in the tank with a new screen, and replaced the filter. I've been about three thousand miles since then, with no trouble until the other day. It started to hesitate, then it would pop when you gave it the throttle. Idle was fine, cruise was okay, but it was as if the TPS wasn't reading WOT or something. Next day, I stopped for a filter and a new screen. It didn't start in the parking lot. Ran just as bad after replacing the filter, but got me where I was going. There, I replaced the pump again. Problem solved, ran like new. For a day.
Now, it runs like nothing is wrong for about ten or fifteen minutes. Then, it begins to hesitate, a little more, and dies for a second or so. It'll do that like clockwork from that point on. I notice a bit of hesitation around and over 3k rpm, as well. It only seems to quit when I'm cruising or accelerating. It dies every minute or so, but comes right back, and runs fine again.
I want to say the pump was the cheapest you could get from rockauto. I ordered it for a piece of rubber I needed, and set the rest aside. At $20, I have little faith in the replacement pump. The screen on the other pump came out looking fine, but the contents of the fuel filter were not good looking at all. Quite black, pouring from the tank side. I initially diagnosed it as a vacuum problem, and replaced the injector o-rings. I then leveled the intake with a big bastard and replaced the gasket. Once assured the intake was tight, I moved on to fuel delivery. Fuel at the rail looked perfectly clean.
So I've ordered the fuel pressure regulator from Amazon. I'm going to purchase a Delphi pump from a franchise I'm not going to mention here, because they offer nationwide lifetime warranty replacement, but their service is the worst. You already know who it is.
My rail has no valve to install a pressure gauge.
I'm posting here because I need this Jeep to run all of the worst trails in the Guadalupe Mountains this weekend. Otherwise, I may chance it on a 90 which followed me home yesterday and I know pretty much nothing about. Any help is greatly appreciated.
Thought I might add, the only code it registered was lean condition indicated a couple of times. In the last two days, no check engine light.
