We are dealing with a 90 xj 4.0/AW4/231. Well, here is the story.
I was taking it on a country cruise and started to get low on gas. So I stopped to fuel up. After fueling up I started the jeep up without a problem. I started to drive away and the jeep started to buck and miss. It finally shut off, it would crank over but would not start.
I checked for fuel pressure at the rail and there was nothing. So I got the tools out and took off the fuel line between the pump and the filter. The pump was kicking on but not pushing anything out. So, onto the trailer it went.
Now that it is home I can investigate. I tried to start the jeep and it fired right up after sitting on the trailer for a week. So off the trailer and took it for a ride. It would run without a problem until you tried to give it a good amount of the skinny pedal. Then it would just start to miss and want to die. If I apply more pedal it makes it worse and almost dies. If I leave it alone when it starts to die, it will recover on its own and drive without a problem, kindof like it's building fuel pressure in the system again.
So, the first thing I tried was taking out the fuel pump and replacing the screen. I was just going to replace the pump with one I have on the shelf but I would figure I would try this first, as the one on the shelf is a little different. Changing the screen filter did not fix the problem. The next thing I am going to do is replace the pump. I don't know if something clogged it to prevent full operation of the pump.
Any other ideas out there to this problem. Sure would like to go and play in the snow again.
