Question about 1994 Jeep Grand Cherokee
Fuel pumps bind up when they are beginning to fail. as the pump motor wears it starts to overheat, causing the armature to get stuck. Dry gas likely has some cooling effect and banging on the tank jars the armature free.
Replace the pump assembly and you should be good to go!
