That's NOT your problem.

Are you sure?
First off where did you find that OBD I code 82 for a 96 S14 is CKP sensor? And if it's a 1996 car (the year that OBD II was mandated to take effect federally) why aren't we looking for OBD II codes?

Also keep in mind that Speed Density, Density Speed and MAF Systems all require the signal input from the CKP sensor to tell the engine it is underway and should be firing and pulsing fuel. The distributor signal is used to determine exactly which cylinder to be firing at what time in conjunction with the CKP sensor signal. And a CMP sensor signal is even more useful when determining exactly which port to inject into if the engine is designed with sequential (as opposed to bulk/batch/group) port injection. CMP sensor input will also determine which cylinder to fire if the engine management system is DistributorLESS.

However, all of these are based on your CKP sensor signal input first to determine engine speed and often relative position.
