Check and Bleed Fuel Pressure

JH Diesel Flipped His MegaTruck Into Cleetus' Pond...Now We See If It Runs! (6.0 Powerstroke)
What happens here
After confirming the starter is mechanically sound, the focus shifts to the fuel system. A fuel pressure gauge is checked to ensure adequate pressure. The reading is initially below 20 PSI, which is insufficient for a diesel engine to start reliably (a healthy 6.0L diesel typically needs around 60 PSI). To address this, the mechanic uses a wrench to loosen a fuel line fitting near the engine, allowing air and any potential water to bleed out of the system while the ignition is cycled. This process is repeated until the fuel pressure gauge consistently shows pressure above 60 PSI, indicating the fuel system is primed and free of air locks.
Goal: Ensure the fuel system has adequate pressure and is free of air and water.
