To fix the tachometer on a Nissan GA14 engine, first check the connections between the tachometer and the engine's ignition system, ensuring that all wiring is intact and secure. Inspect the tachometer itself for any signs of damage or malfunction. If the wiring is fine, test the tachometer with a multimeter to determine if it’s receiving the correct signals from the ignition coil. If necessary, replace the tachometer or the ignition coil to restore proper functionality.

To fix the tachometer in a 1996 Nissan 240SX, first, check the wiring and connections behind the gauge cluster for any loose or damaged wires. If the connections look good, inspect the tachometer itself for any signs of malfunction, such as a broken needle or burnt-out bulbs. You may also want to check the ignition system, including the coil and distributor, as issues there can affect the tachometer's performance. If all else fails, consider replacing the tachometer or the entire gauge cluster.
run a new line to the distributor.
To fix the tachometer on a 1999 Isuzu Trooper, first check the vehicle’s fuses to ensure none are blown. If the fuses are fine, inspect the wiring and connections at the tachometer and the engine’s ignition system, as loose or damaged wires can cause issues. Additionally, consider testing the tachometer with a multimeter to see if it’s receiving a signal. If these steps don’t resolve the issue, the tachometer may need to be replaced.
It depends on what is wrong with it.The tachometer takes input from the revolutions of the engine, so can you identify if the connection in the engine is okay, or if the connection to the actual guage(tachometer) on the dash is okay.A test would be to get a working instrument panel,replace yours and see if the rev-counter(tachometer) works. If it does then it might be cheaper to replace the whole instrument panel. If it does not then the problem might be in the engine, you might want an auto-electrician to trace the cables etc.
That means that the bearings of the mechanism have failed. It is not economically practical to repair the tach. You'll need to replace it.
you have to replace it
Check the speed sensor
To fix a faulty tachometer light, first check the vehicle’s fuse box for any blown fuses related to the instrument cluster. If the fuse is intact, inspect the wiring and connections behind the dashboard for any loose or damaged wires. If those elements are in good condition, the issue may lie within the tachometer itself or the vehicle's engine control module, which may require professional diagnostics or repair.
To fix a non-working tachometer on a 1997 Ford F150 with a 4.6L engine, first check the connection at the back of the instrument cluster for any loose or corroded wires. Next, verify that the signal from the ignition system is reaching the tachometer by testing the signal wire for voltage with a multimeter. If the wiring is intact and the signal is present, consider replacing the tachometer itself or checking the powertrain control module (PCM) for issues, as it controls the signal sent to the tachometer. If the problem persists, consult a professional mechanic for further diagnostics.
if you try to start it and it wont turn over it could be the timing belt. goodluck finding someone to fix it...
check your idle control valve located behind the engine
