Visual Engine and Chassis Inspection
- Verify that there are no fluid or pressure leaks.
- Inspect all wire connections for damage.
- Inspect the manifold absolute pressure (MAP) hose. charge air cooler (CAC) hoses, and intake for leaks.

Fuel, Oil, Coolant, Hoses, Leaks and Electrical System:

Recommended Procedure:
- Inspect for a hole in the MAP sensor hose or a pinched hose.
- Inspect the fuel system, including the fuel tank, fuel pump, fuel filter housing and fuel lines, for kinks, bends or leakage.
- Inspect for coolant leaks at the radiator and coolant hoses. Check the coolant level.
- Inspect wiring for correct routing, and verify no rubbing or chafing has occurred.
- Inspect all sensors, and verify the connectors are completely seated and in good condition.
- Inspect the CAC hoses for leaks.
- Inspect for battery terminal corrosion.

Possible Causes:
- Loose or leaking fuel lines
- Kinked or blocked fuel lines
- Fuel or oil leaks
- Coolant leaks
- Pinched or open MAP sensor hose
