WARNING: This page is about a different car, the 2005 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

NO.6 CRANKS NORMALLY BUT WILL NOT START [BP, BP WITH TC] DESCRIPTION & POSSIBLE CAUSE

6	Cranks normally but will not start
DESCRIPTION	Starter cranks engine at normal speed but engine will not run. See NO.5 ENGINE STALLS-AFTER START, AT IDLE if this symptom appears after engine stall. Fuel is in tank. Battery is in normal condition.
POSSIBLE CAUSE	No battery power supply to PCM Air leakage from intake-air system Open PCM GND or vehicle body GND Improper operation of IAC valve EGR valve malfunction No signal from CKP sensor or CMP sensor due to sensor, related wire or incorrect installation Low engine compression Vacuum leakage Spark leakage from high-tension leads Poor fuel quality PCV valve malfunction ACL restriction Restriction in exhaust system Disconnected electrical connector Open or short circuit in FP and related harness Inadequate fuel pressure FP mechanical malfunction Fuel leakage from injector Fuel injector clogged Purge solenoid valve malfunction Immobilizer system activation 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 injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete "BEFORE SERVICE PRECAUTION" and "AFTER SERVICE PRECAUTION". (See BEFORE SERVICE PRECAUTION ) (See AFTER SERVICE PRECAUTION ) CAUTION: Disconnecting/connecting quick release connector without cleaning it may possibly 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.
