Check Coil

Ensure ignition coil is disconnected. Using a DVOM, measure resistance of ignition coil between primary wire terminals (Blue wire and Yellow/Blue wire terminals). Measure resistance between ignition coil secondary terminal and positive primary terminal (Blue wire terminal). See the IGNITION COIL RESISTANCE  table for specification. If readings are not within specification, replace ignition coil. If ignition coil resistance is okay, go to next step.
