Question about 1991 Jeep Cherokee Briarwood
First, check ignition system...cap, rotor, wires & coil. You may have some arcing going on there. If plugs are not recent, take a look at them as well...even if they are good, they can often tell you which cylinders are having a problem (wet with fuel, heavy deposits or just "different" from the rest) You may not hear the fuel pump come on all the time if the pressure in the line is not bleeding down. I would take a look at the relay first (power in & out). If fuel filter is more than 1yr old change that. (routine maintenance regardless of problems) Pressure test system if in doubt. Make sure idle air system is clean and do a quick test on crank sensor (a known problem area). likely something here will get you going.
