Chrysler Full-Size Trucks 1997-2000 Repair Guide

Diagnosis and Testing


Component tests are limited to checks of the spark plugs and coils. Specialized analysis equipment is needed for more in-depth troubleshooting.

Do NOT run the engine with a coil disconnected. Do NOT attempt to ground a coil to the engine to check for spark. Sensitive components could be ruined or the extremely high voltage could cause serious injury or death.
