Check to see if your truck was recalled for a faulty cam shaft sensor. Some sensors develop hair line cracks which allow contaminants to get in and the sensor becomes intermittent. The symptoms can include sudden shutdown of the engine so a recall was issued.

Is there a fuse for the tachometer?

Most vehicles power the tach from the same circuit as the other instruments. So if the speedo and fuel gauge work the tach probably has power. May not have a ground signal from the engine computer.

Tachometer on my 1986 fiero gt is out of calibration it ,engine runs right but tachometer is off the graphs limits.

There's a good chance that the tachometer switch setting on the tachometer is broken. They use the same tach for different engine sizes and change the amount of cylinders with the switch. You might have to replace the tach

Tach. drop's to zero while driving 70 ?

I have had the almost same problem twice. A 'thump', like the engine missed a fire and tach drops. Seems OK after restart. Electrical? Timing chain slip?
Has 135,000 mile. Any clues?

Engine misses badly at freeway speed and problem gets worse uphill. The tachometer gyrates wildly. Finally lost power and stopped. Waited a few minutes and restarted, but barely made it home. Engine...

spark plugs? spark plug wires? coil? if it shuts off when hot, and starts when cold, coil could be problem....could be radiator stopped up causing it too heat, and will go off wait a few and it'll start back up...

Tachometer fails to work all of the time

You will need to remove the tach and have it repaired by a factory authorized service center, don't go through the dealer, they will 2X the price.
