On my 93, the tach will read about 300 rpm while cranking. Once the truck is running, the tach is dead. I even held the key in the "start" position after it started and it still dropped to 0. I did this thinking that power was getting cut to the guage in the run position. I also removed the sensor and clean it. No luck. I know the sensor can be checked, but it there anyway to check the tach itself?
