harness under the valve cover is OK. The problem is in the windings of
the injector solenoid. Replace the injector (WP 0114). Verify that the
repair eliminates the problem.
(2) If the Injector Solenoid Test does not indicate OPEN for the suspect
injector, the problem appears to be in the engine harness under the
valve cover. Replace the harness under the valve cover or repair the
harness under the valve cover (WP 0090). Run the Injector Solenoid
Test in order to check the installation of the new harness before installing
the valve covers. Verify that the repair eliminates the problem.
If the problem is not resolved, there may be a malfunctioning cylinder that is
caused by a mechanical problem. Replace the engine.
