Won't start no codes

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 truck. If your Silverado 2500 HD cranks and starts but immediately dies without any codes, it could be related to a fuel delivery or immobilizer issue. Since fuel pressure is good, the problem may lie in the fuel injection system or with a sensor like the crankshaft position sensor, which can cause stalling without triggering a code. Another possibility is an issue with the anti-theft system. If the key fob or immobilizer isn't recognized, it can shut off the engine. 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!
