Hey all - I have a 2006 2500 Duramax Diesel with about 93,000 miles. Driving up from SoCal today and stopped and had no problem starting back up earlier. Then tonight, I pull into the hotel and then go back out to move the truck and Bam, it turns over, but won't start. The headlights dim/cut out when I turn it over, but there is no starting. There are new batteries, clean connections. So, here I am, knowing I'm not where I can fix it, no anyone who is a good mechanic, and just don't want to get ripped off. So, I'm thinking either starter or fuel pump? Sound in the ball park?
