1986 Camaro V-6, 2.8 mpfi . Electric fan energized when cold and stays on. Does not cycle on/off. When restarted warm fan does not energize when hot.
What's happening here?

You can diagnose with this schematic. Sounds like a faulty ecm.

The schematic doesn’t show it . The fan might have a switch in your cylinder head.
When grounded the fan turns on. What codes are you getting 15 ?
No need to start two posts on the same topic.
