I have a 96 model XJ. I was on my way home from a long trip Tuesday. I was was using cruise control on a flat road at 65 mph at about 2100 rpm. The engine started sputtering as though I was running out of gas (I had a half tank). I turned off cruise control and pumped the gas peddle and the vehicle started running ok. But, it would sputter intermittantly. I was able to make it to a gas station where I checked vacuum lines (they seemed ok) and topped off the gas tank. I let the engine cool down a bit before continuing on home. I was able to make it home (about 90 miles) cruising between 55 and 60 mph, but it still sputtered a little every now and then. It seemed more apparent when going up hills. The vehicle runs araound town with no problem.
I was reading the fuel pump test in my Chilton's manual. It says my fuel pressure should be 31 psi at idle. To disconnect the vacuum line to the pressure regulator and the pressure should go up to 39 psi. On my Jeep the fuel pressure regulator is part of the pump assembly and doesn't have a vacuum line to it. How do I check my fuel pump?
Do ya'll have any other ideas on what could be the cause of the trouble? I'm going to check my plugs, wires and distributor cap as well.
Thanks,
