Please help me!!!

What is your question?

Replaced battery alternator checked anything I can think of & my car won’t charge radio turns on then off repeatedly when it does start & drains a fully charged battery in seconds. I’ve checked fuses and relays also noticed beforehand my headlights went out and park lights after that…replaced the plugs now they do work but car won’t stay running very long at all. Could it be my tipm? Or computer considering my voltage regulator is located in my pcm? Plz help located in atkins Va!

What makes this problem better or worse?

Maybe a bad ground?? Fuse box?? PCM?? Radio issue?
