Hello and thank you for using JustAnswer. My name is XXXXX XXXXX I will do my best to help you with your Cadillac problem.

The problem is not the alternator. The alternators job is to charge the battery after the engine is running. Your problem is likely either going to be fuel related or igniton related. Fuel related failures are more common. Take the air intake tube loose at the engine and spray starting fluid into the engine while cranking. If the engine starts, the problem is fuel related, most likely a failed fuel pump.
