GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi, I’m Ron and I’ll be helping you today.Before we get started though, Please understand that I don't knowyour skill level or tools you have to assist us. Also understand thatI can't see, smell, hear, or touch the vehicle either, so patience isappreciated. JA is a great Q/A site, but it does NOT replace arepair shop.My goal is to make you happy and get a great rating in return formy time. Sometimes I have to give you bad news that I know youdidn’t want to hear, so please don’t shoot the messenger.
Let's start with checking for spark at the plugs with a spark tester, then check fuel pressure with a gauge. let me know your results. Thanks, Ron
Hi again, just following up on your question. Do you need any more help?
