You can determine if the control module is malfunctioning in a 1994 Caprice Classic by observing symptoms such as erratic engine performance, poor fuel efficiency, or dashboard warning lights. Additionally, issues like difficulty in starting, stalling, or problems with transmission shifting may indicate a failing control module. Diagnostic trouble codes (DTCs) retrieved from an OBD scanner can also provide insight into control module problems. If these symptoms are present, further testing or replacement of the control module may be necessary.
The only 100% sure way to know is to remove the starter and have it bench tested at an auto parts store.

If a catalytic converter is indeed bad, it's far more cost-effective to replace it rather than try to repair it
