1993 GMC Yukon Q&A
1993 GMC Yukon Question: My truck runs great the first 30 minutes of me driving it then after shuts off.
Runs well when i first drive and after driving it for over 30 minutes or so when i come to a complete stop it shuts down. Also after the truck has been running for over an hour and i turn the truck off it will not start back up untill it cools off. Any ideas of what it could be ? - jorge jr
When it will NOT start is when a mechanic needs to test for correct fuel pressure and ignition fire! - pushrod
