Check the wiring for continuity or shorts between the synchronizing switch and the ECM.
Check the wiring for continuity or shorts between the throttle position sensor and the ECM.
Check the wiring for continuity or shorts between the ECM connectors. Check the synchronizing switch for proper operation.
Disconnect the wiring from the synchronizing switch.
Use a voltmeter to check the resistance across the contacts of the synchronizing switch as the synchronizing switch is turned to different positions.
