Diagnosis: This is often caused by a failing 6251-71-8210 transfer pump. If the pump cannot maintain fuel pressure, the engine starves for diesel. Check for fuel leaks around the pump body or air bubbles in the fuel lines.
Solution: The internal check valve of the 6251718210 pump might be worn, causing fuel to drain back to the tank. Replacing the feed pump ensures immediate fuel availability upon cranking.
