temp and fuel gauge dont work

would like somemore info becuase the more I read on this problem, ppl seem to have diff answers. So I have a 1995 yj 2.5l, the temp gauge and the fuel gauge dont work. Ive read that it could be in the tank itself, then I read on another forum that if the fuel gauge reads at the F line all the time, that it could be the ground. Then I read about the temp sending unit bieng located under the drivers side dash, and under the in back of engine. Help.. O and has soon as I turn on the jeep the temp gauge moves slightly and thats about it. And yes Ive gone threw so many forums already but at this point just confused.

Temp gauge sensor for the gauge is on the drivers side cylinder head rear. Single purple wire. Ground the wire out the gauge pegs high. Fuel gauges are sent a signal from inside the tank from the sending unit. They read 0-95 ohms IIRC. If the gauge is reading hitgh all the time yes it could be a bad sending unit input. Requires tank removal to replace or repair. Or just cut an access hole in the tub over the tank to gain regular access to the pump and sending unit.

Welcome to the forum!!! I just noticed so edited.

It is not the ground issue. The fuel pump shares the ground with the guage. The ground issue would kill your fuel pump.
