Hey, since it sounds like you guys know your stuff I'd though I would get some of your input on my problem. I just bought my first diesel from a private seller for 24k. Amazing looking truck with only 79,000 miles on it. However, a week after I bought it I'm having trouble with it. After it warms up it seems to not want to start. It will sound like its starting three times and after that all you hear is a click when you turn the ignition. It has a brand new starter, all the relays have been checked, and the batteries. I think it might be the high pressure oil pump. Thoughts?
