I went wheelin' at Uwharrie this weekend and a few times on the trails my engine would bog down like it was about to die and I'd have ZERO power. this would go on for a few minutes and then the jeep would run normall, then it would do it again at random. It seemed a bit better after I let it sit off for a while while the rest of the group went ahead and tackled the obstacles.
It also does this on the road at about 30-35 mph in 3rd (i think) gear. It won't accelerate at all and I get loud pops from the intake, like it's backfiring. I say intake because after the dusty trip at URE I could see dirt pop out from under my hood when it backfired. It also boggs down at random high speeds on the highway when I try to accelrate, however this is very infrequent.
My next problem is that it takes FOREVER to start. I let the fuel pump prime and build up pressure, then I start it, and it takes about 5-10 seconds before it cranks over, stumbling and sputtering until it finally starts up. A nice fellow with a white 91 XJ with a longarm kit told me that it was my check valve in my fuel pump.
Sooo Would replacing the fuel pump fix the problem? I have a new 02 sensor, plugs, wires, cap and rotor and everything else is in good shape. My injectors are also new.
If so, how much of an ordeal is replacing the fuel pump? Do I just drop the tank and pull it out?
