Hi, I am a first time diesel owner and just purchased a used Silverado 2500 HD with Duramax and Alison transmissioin. I took it out last Friday with my boat and it broke down at the gas pump. I turned off the truck to refuel and when I went to start it it took a few attempts to start and then died as I put it in park. It had no problems turning over but semed to not be getting fuel. Long story short, I got it to the dealer but am waiting for the diagnosis. any ideas on what may be the problem and if it's covered under the powertrain warranty or any other warranties? I fell in love with this truck the first time I hooked my boat up to it but I'm feeling a little cold after it stranded me. Any help, suggestions or condolences are appreciated.
