COMMENT

｠

In such cases as the above, the cause is usually
improper air/fuel mixture. It is possible, though less
likely, that the spark plugs are generating sparks but
the sparks are weak.

TROUBLESHOOTING HINTS (The most likely
causes for this case:)

｠

Malfunction of the fuel pump system.

｠

Malfunction of the ignition system.

｠

Malfunction of the injector system.

｠

Poor compression

｠

Malfunction of the EGR system

｠

Contaminated fuel.

｠

Malfunction of the ECM.
