Still have a question




Do your best to listen to CFI-EFI, or at least pay attention to what he is saying. His knowledge will get the problem solved for the lowest cost. Nobody wants to spend money on wild goose chases.
When you ask for help, it’s always wise to do your best to help others help you. If the person who has the knowledge to help you needs to “dig” for too much information, they may not offer.
In this case CFI-EFI is trying, even if you don’t think he is. Even without actually helping with your Corvette problem, he is giving you some excellent advice for your future issues
This is the proper way to ask for help. So that there is no confusion, certain things can be done with the engine running other things should NOT be done with the engine running.
Do NOT short pins with the engine running.
Do NOT disconnect neg term of battery with engine running.
If you have a scanner it will work while the engine is running.
