Run a few blocks then dies

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your F-350. Since your truck has been sitting for two years, it's likely dealing with stale fuel, clogged fuel lines or filters, or other issues related to sitting unused. The behavior you described points to a possible fuel delivery issue, such as a failing fuel pump or a restricted fuel system. You might also want to check for vacuum leaks and inspect the ignition system for wear. Start with draining the old fuel and replacing it. Replacing the fuel filter and adding a fuel system cleaner to the tank could help improve fuel delivery. It might also be a good idea to check the fuel pump's pressure and ensure the tank is free of rust or debris. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
