Your temp sending unit off of your engine is either disconnected or faulty look into we're the wire leads into the sending unit it's usually were your upper radiator hose meets up with the block or were your thermostat housing is thanx Chris
When the gauge doesn't work, you have to determine, is it the gauge on the dash or the temperature sending unit on the engine or a wiring problem. Try this: find the sending unit on the engine and pull the wire off it. With the ignition key on, touch the wire to a metal ground on the engine. Does the temp. gauge move? If it does, replace the sending unit. If it doesn't move, replace the temperature gauge on the instrument panel.
Was this the original problem with the gauge? If so you have problem with a wire shorting to ground from your sending unit to the gauge. If the problem arose as a result of the sending unit replacement, the new sending unit is defective.
To review, you have two temp sensors, one for the gauge on the dash and one for the computer. If you unplug the sensor for the computer the reading will be minus 30 degrees or over 300 which will make it very hard to start. Unplugging the sensor for the gauge would have no effect on the computer. According to the wiring diagram, the wire for the temp gauge is green, and the wires for the temp sensor for the computer are yellow and black.
For electrically operated temp gauge, check the power supplying it. Most often, this is connected to either the accessory fuse or front dashboard instrument panel, check for busted fuse at the fusebox. If every fuse is okey, then your temp gauge needs replacement.
