The tachometer is fed from the distributor coil. High voltage spikes are filtered on the wire to prevent damage to the electronic display. There is a tach filter attached to the intake manifold. Replace this filter and your tach will work again. Mid-America Motorworks Part #618-561

No, the 1984 Corvette does not use a traditional ignition key like most vehicles. It features a specialized key that includes a chip for the vehicle's anti-theft system. This means that standard keys won't work in the ignition, and a specific key must be used to start the engine.
