NO.6 CRANKS NORMALLY BUT WILL NOT START [MZR-CD (RF Turbo)]


6	CRANKS NORMALLY BUT WILL NOT START
DESCRIPTION	• Starter cranks engine at normal speed but engine will not run. • Refer to symptom troubleshooting "No.5 Engine stalls" if this symptom appears after engine stall. • Fuel is in fuel tank. • Battery is in normal condition.
POSSIBLE CAUSE	• Poor fuel quality • Intake-air system restriction • Fuel line restriction • EGR system malfunction • Glow system malfunction • Inadequate fuel pressure • Fuel pressure sensor or related circuit malfunction • Suction control valve malfunction (built-in supply pump) • Fuel pressure limiter malfunction (built-in common rail) • Fuel leakage • Fuel filter clogging • Incorrect fuel injection timing • Erratic signal from CKP sensor • Erratic signal from CMP sensor • V-reference supply circuit malfunction • ECT sensor or related circuit malfunction • Accelerator pedal position sensor or related circuit malfunction • MAF/IAT sensor or related circuit malfunction • Supply pump malfunction • Fuel injector malfunction • Immobilizer system and/or circuit malfunction • Low engine compression • Improper valve timing • IDM or related circuit malfunction • PCM control repay malfunction Warning The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before performing the fuel system services: • 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 injury 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 manual. (See BEFORE SERVICE PRECAUTION [MZR-CD (RF Turbo)].) (See AFTER SERVICE PRECAUTION [MZR-CD (RF Turbo)].)
