My 2001 silverado shows 2 codes, P0200 and P0300. I would like to know what has to be done to correct these error codes? Thank you, allen

Does the vehicle start and run? P0200 means injector circuit open, that might mean all of them.

The P0300 is a random misfire, usually a problem common to all cylinders. I'd check the injector issue first. B+ to the injectors goes hot with the key on. Now if the computer isn't grounding the injectors, that's another issue.
