- Crank the engine for up to 30 seconds.
- Observe the Engine DTC information with a scan tool.
- If any of the following DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle to diagnose those DTCs: P0201-P0206, P0335, P0336, P0351-P0353, P0601, P0602, P0603, P0604, P0606, P0607, P060D, P062F, P0685, P0689, P0690, P1516, P2610
- Observe the engine speed parameter while cranking the engine.
- If engine RPM is not indicated, refer to Electronic Ignition (EI) System Diagnosis .
- Install a spark tester.
- Crank the engine for 15 seconds. Spark should be observed from the Spark Tester.
- If spark is not observed refer to Electronic Ignition (EI) System Diagnosis .
- With the ignition ON and the engine OFF, test the fuses that are supplied by the powertrain relay for voltage. The test lamp should illuminate at each test point for the following fuses:
- Emission Fuse
- Ignition 1 Fuse
- If the test lamp does not illuminate on at least one side of each fuse, refer to DTC P0685, P0689 or P0690 .
- Command the fuel pump ON and OFF. Fuel pump should energize when commanded ON and De-energize when commanded OFF
- If the fuel pump does not respond refer to Fuel Pump Electrical Circuit Diagnosis .
- Turn OFF the ignition.
- Install the J 34730-1A
Fuel Pressure Gage. Turn ON the ignition and command the fuel pump ON while observing the J 34730-1A
. The fuel pressure should be between 345-414 kPa (50-60 psi).
- If the fuel pressure is not within 345-414 kPa (50-60 psi) refer to Fuel System Diagnosis .
- Inspect for the following conditions:
- Compare the actual engine coolant temperature to the ECT parameter.
- Air filter and air intake system for restrictions and obstructions
- Test the fuel for contamination. Refer to Alcohol/Contaminants-in-Fuel Diagnosis .
- Inspect the spark plug and spark plug wires. Refer to SPARK PLUG WIRE INSPECTION .
- Test the exhaust system for restrictions. Refer to Restricted Exhaust .
IMPORTANT:
Additional DTCs may set when using the fuel pump output control.
