Engine Will Not Turn When Start Switch Is On Cause: Battery has low output. Correction: Make reference to Item 3. Cause: Wiring or switches are damaged. Correction: Make reference to Item 3. Cause: Starting motor solenoid is damaged. Correction: Make reference to Item 3. Cause: Starting motor is damaged. Correction: Make reference to Item 3. Cause: Oil pressure switch for prelube pump is damaged. Correction: Make a replacement of damaged switch. Cause: Prelube oil pump is damaged. Correction: Repair or replace pump components as needed. Cause: Inside problem prevents engine crankshaft from turning. Correction: If the crankshaft can not be turned after disconnecting the driven equipment, remove the fuel injectors and check for fluid in the cylinders while turning the crankshaft.If fluid in the cylinders is not the problem, the engine must be disassembled to check for other inside problems. Some of these inside problems are bearing or piston seizure. 2. Engine Will Not Start Cause: Slow cranking speed. Correction: Make reference to Items 3, 4 and 5. Cause: Dirty fuel filter. Correction: Install new fuel fitter. Cause: Dirty or broken fuel lines. Correction: Clean or install new fuel lines as necessary. Cause: Fuel pressure is low. Correction: At starting rpm, the minimum fuel pressure from fuel transfer pump must be 20 kPa (3psi). If fuel pressure is less than 20 kPa (3 psi) change the fuel filter element.Look for air in the fuel system. If fuel pressure is still low, check the fuel control valve and the fuel transfer pump for correct operation. Cause: No fuel to cylinders. Correction: Put fuel in tank. "Prime" (remove the air and/or low quality fuel from the fuel system). Cause: Bad quality fuel. Correction: Remove the fuel from the fuel tank. Install a new fuel filter element. Put a good grade of clean fuel in the fuel
