I enjoy your vidoes I love working on cars I have a question about old chevy blazer I have it starts up fine after you drive it around then when it sits overnight it cranks and starts up when the battery is almost dead then starts up every time I ran my scan tool on it and no codes are coming up tripped and ford and chevy shops told me everything is running mechanicly sound idk maybe a ghost lives inside the suv

well, old battery and old engines tend to do that. When it's cold, try a little starting fluid in the air filter. if that doesn't work, replace the battery
