light on fuel are recovery

What??? Please start over. Complete information in complete sentences.

This make no sense.

Confused light off understanding

If you light the fuel you might be in need of serious recovery.

Do you perhaps mean “air and fuel delivery”? I’m going to assume the check engine light is on and you had the code read and it came back as something to do with air and fuel. Post the actual code and someone can probably help.
