No. 5 Engine Stalls-After Start/At Idle: Notes

NO. 5 ENGINE STALLS-AFTER START/AT IDLE REFERENCE CHART (MZI-3.7)

5	ENGINE STALLS-AFTER START/AT IDLE
DESCRIPTION	Engine stops unexpectedly.
POSSIBLE CAUSE	Vacuum leakage Air leakage from intake-air system parts Air cleaner restriction Poor fuel quality Electrical connector disconnection Throttle valve restriction or clogged PCM DTC is stored No battery power supply to PCM or poor GND Erratic signal to PCM APP sensor or related circuit malfunction TP sensor or related circuit malfunction Improper operation of drive-by-wire control system Restriction in exhaust system No signal from CKP sensor due to sensor, related wire or wrong installation Ignition coil or related circuit malfunction Spark plug malfunction Fuel leakage from fuel injector Fuel injector clogging Inadequate fuel pressure Open or short circuit in fuel pump body and related wiring harness Fuel pump body mechanical malfunction Fuel line clogged Pressure regulator malfunction (built-in fuel pump unit) Fuel leakage from fuel system PCV valve malfunction A/C system operation is improper Purge solenoid valve malfunction Air leakage from intake air system when the engine runs high speed Improper operation variable valve timing control system Low engine compression Improper valve timing WARNING: The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before servicing the fuel system: Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel. Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete "BEFORE SERVICE PRECAUTION" and "AFTER SERVICE PRECAUTION" described in this service information. (See BEFORE SERVICE PRECAUTION article.) (See AFTER SERVICE PRECAUTION article.) CAUTION: Disconnecting/connecting quick release connector without cleaning it may cause damage to fuel pipe and quick release connector. Always clean quick release connector joint area before disconnecting/connecting, and make sure that it is free of foreign material.

ENGINE STALLS-AFTER START/AT IDLE

DESCRIPTION

WARNING:
The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before servicing the fuel system:
- Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
- Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete "BEFORE SERVICE PRECAUTION" and "AFTER SERVICE PRECAUTION" described in this service information.
