General Information

malfunction, refer to the individual system troubleshooting charts to
isolate the specific cause.

Engine Troubleshooting Guides

EFI Engines Only: Refer to EFI Diagnostic Service Manual.

These guides were written to help you trace the symptoms of the
trouble to the source, without having to read through and prove every
possibility. Much of the information here will be familiar to well in-
formed mechanics.

Also, many factors will seem insignificant but when you think of it,
usually the toughest problem to troubleshoot is caused by the small-
est error. The greatest aid to solving a service problem is informa-

System Isolation

Engine Does not Start

Cranking System

Engine should crank at specified RPM. If not, check for
