If you meant fuel guage, most likely the sender unit inside the tank has a problem. To test, find the wire going to the sender and ground the wire briefly to see if guage needle goes up. If so, replace sender.

I have a GMC Envoy 2003 the dash guage does not work how do I figure out the problem is it a guage or fuse or sender unit

You will have to unplug the in-tank unit's connector,and figure out which wire is the fuel level sender.If you ground it,the gauge will go to full or empty(can't remember which)and it will go to the opposite extreme when you unground it.(Most likely the sender is bad,and if you are pulling out the in-tank unit,do yourself a favor and replace the fuel pump at the same time).

Where is the sender unit for my Mitsubishi L300 fuel guage

The fuel sender in located inside your fuel tank. it will most likely be screwed to the side or the top of the tank so you may need to remove your tank to gain access The fuel hose(s) go to the same place so simply trace the fuel hoses back to the tank. Some vehicles have an access panel in the floor of the van so check for this. To test the fuel gauge, turn the ignition key to ON ( warning lights lit but do not crank the engine), remove the wire to the fuel sender and ground it to the body of the vehicle - the fuel gauge should go tho the FULL mark if all is Ok

You may have a bad guage. To check, ground out the sender by placing a screwdriver or alligator clips accross the ground tab and the center positive terninal. If the guage works you would normally expect a sender problem, but since you put on a new sender (assuming it's wired correctly [ no offense ]) you will need to trace t the wires from the guage to the SU. The fuel guage power lead is pink ( or at least it is on boats ) Look for a bad connection, corrosion, frayed wires or anything else that looks abnormal. You may want to simply replace the existing wire temporarily with another wire. This new wire should tell you immediately if your guage is bad. Good luck!

Low Fuel Pressure on Landrover Freelander TD4

From 53 reg onwards, diesel pump is under R.H. rear wheel arch, hidden by the plastic wheel arch liner. Older versions have combined fuel pump/sender in the tank (under R.H part of rear seat).
You should be able to hear a faint purr from the pump when ignition is turned on but engine not yet running.

Temperature Guage, '89 Camry

the cable going from the gauge to the sender unit is an earth return. if you take it off the sender unit wire if the gauge does read hot the sender and earth it out the gauge should go to the hot segment.dont leave this cable to earth very long do it quickly. if the gauge does read it is ok, there is no earth to the petrol tank. if it does not read it will be faulty. hope this helps.

Sub Fuel Tank

Very Hard!!!! There are no specs on this, the only way out is to go to your nearest dealer and look at a sender unit and measure its resistance and compare the 2 sender units resistance. It should be measured in Kilo holms, the way to measure it is read the resistance when the floats at its 'lowest' point, and the resistance sould either increase or decrease when you move the float 'up', this depends on what resistance the fuelguage requires, to test if the fuel guage works,'take the positive cable that plugs into the sender unit, fuse it with a low ampeage fuse and connect it to body/chassis while key 'on' and check fuel guage, it must go to full position, there could be another problem, check cables for opencircuits, and check earth(-)connection to the sender unit, plse post to me for further assistance Mishdaman.....
