i just got a new unit and the tach doesnt read and also the alternator wont charge so what could be the problem, i checked if the crank sensor is still there and it is but can it go bad? what are your thoughts??? THANKS

Try moving the sensor closer to the crank pulley, Use a piece of paper if you dont have a feeler gauge. The alternator wont charge if PCM isnt gettin a crank signal.
