NOTE: For SDI and Power Tek engines,refer
to ENGINE MANAGEMENT for more information
concerning the Engine Control Module (ECM).
When other components have been tested above
and are good, the electronic module can be sus-
pected. Ensure wiring and connectors are in good
condition and perform the following tests prior to
replacing the electronic module.
Disconnect the connector housing between mod-
ule and high voltage coil.
