1. VISUAL ENGINE/CHASSIS INSPECTION

NOTE: For a hard start/no start concern with the engine oil temperature (EOT) below 15°C (60°F) carry out Step 11 first.

NOTE: The camshaft position (CMP) sensor, crankshaft position (CKP) sensor, injection pressure regulator (IPR) and the PCM connectors are the most critical electronic sensors and actuators to inspect in no start situations.

Purpose:
The purpose of this test is to check the general condition of the engine and look for obvious causes of a hard start or no start condition.







Recommended Procedure:
Inspect the fuel system, including the fuel tank and the fuel lines for kinks, bends and/or leakage. Inspect for coolant leaks at the radiator and the heater hoses and check the coolant level. Inspect the manifold absolute pressure (MAP) sensor and the charge air cooler (CAC) for pinched hoses and leaks. Inspect wiring for correct routing and make sure no rubbing or chafing has occurred. Inspect the engine harness, fuel injector control module (FICM), powertrain control module (PCM) and sensor connectors to make sure they are completely seated and in good condition.

Possible Causes:
- Loose or leaking fuel supply lines cause the fuel system to lose its prime
- Kinked or blocked fuel supply lines
- Fuel or oil leaks contribute to no start conditions
- Coolant leaks indicate engine problems
- Electronic connectors may be damaged or incorrectly installed causing a no start condition
- Pinched or open MAP sensor hose
- Pinched or open CAC hose
