Choke problems for a 454 Chevrolet engine choke light is on but the open what do i do?

1. Check the choke linkage. Make sure that the choke linkage is properly connected and that there is no binding or interference. If the linkage is damaged or disconnected, it will need to be repaired or replaced.

2. Check the choke pull-off. The choke pull-off is a vacuum-operated device that helps to open the choke valve when the engine is running. If the choke pull-off is not working properly, it will need to be replaced.

3. Check the choke thermostat. The choke thermostat is a temperature-sensitive device that regulates the amount of vacuum applied to the choke pull-off. If the choke thermostat is not working properly, it will need to be replaced.

4. Check the carburetor. If the choke is still not opening after you have checked the linkage, pull-off, and thermostat, the problem may be with the carburetor. The carburetor may need to be cleaned or rebuilt if it is not working properly.
