Question about 1994 Jeep Grand Cherokee
If the inside of the tank is clean and the pump is not being forced to drink garbage, the only things that can cause that is running with very low fuel, a poor ground or a breakdown of the power lead that appears as if the pump is bad but it just isn't getting sufficient voltage.
It is possible for a pump to fail if the charging system is overcharging, but generally that will cause other problems as well. Running volts should never go higher than 14volts.
It's also unlikely that you have just gotten a bad batch of pumps...it does not often happen but it can.
Far more often it turns out to be one of the items I mentioned, so check all those first.

Much as i hate to say this. If you are buying aftermarket fuel pumps, stay away from carter. For whatever reason they have a huge comeback rating for jeeps. They dont seem to be built to spec.
