1996 Other Chrysler Models engine control module [`computer]

The engine wouldn't run unless the computer was at least partially functional.

If the CEL lites for the bulb check, when you turn on the key, that means the computer is awake. With the key on, you can also check for reference voltage at one of the engine sensors, that use a ref voltage. The ref voltage comes from the computer.

Even with all this, the computer could still cause a problem on a individual system. What ever the problem, can you check for troublecodes?
