Installed new fuel pump 98 town and country ox now gas gauge stopped working

Chances are when the pump was put in the tank the float on the side of the fuel pump was not turned to where it will move up and down properly with the fuel level. Or it might have been forced in causing damage to the sending unit cause they can be kinda tricky to get back in the tank and turned in the right position. Pump will have to be removed and sending unit on the side of the pump inspected. However before doing all that make sure all the wires are plugged into the top of the fuel pump. Good luck

Fuel indicator needle doesn't move to fuel level

Most likely its the sending unit in the fuel tank. Your sending unit is probably one unit with the fuel pump. Very rarely is it the gauge in the dash. Your local friendly mechanic can take care of that for you.

A few things could end with these results. A faulty Fuel Sending unit, an issue with the gauge directly or a poor connection at the sending unit its self. I would start with the wiring and go from there. Check at the fuel tank where the wiring connects for the fuel pump and sending unit for corrison, a good cleaning and some ***-electric grease will do wonders.
