Ignition C(3)I - No Start/No Spark Diagnosis

Number 86-6 (Gasoline) - 55 Date 7/86
Subject: C(3)I NO START/NO SPARK DIAGNOSIS


1985-86 MODELS EQUIPPED WITH 3.0L V6 ENGINES


When diagnosing a no start/no spark condition on C(3)I ignition systems, make sure the C(3)I ignition module is bolted to its mounting bracket. Failure to bolt the module to its bracket eliminates the module's path to ground. The module must be properly grounded in order to continue diagnostics and keep from replacing good modules.
