Timing Check

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 1987 Ford Ranger, 1987 Ford RV Cutaway, 1987 Ford Pickup, 1987 Ford Econoline, and 1987 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If engine will not start, go to TEST A - NO START . If engine starts but stalls while testing, go to DIAGNOSIS BY SYMPTOM  TEST.
  1. Turn ignition off and wait 10 seconds. Verify that SELF-TEST has been activated. Restart engine and check timing while in SELF-TEST mode. You are allowed 2 minutes to check timing from the time the last code is displayed.
  2. Correct SELF-TEST timing equals base ignition timing (10° BTDC on all engines) plus 17-23° BTDC. If timing is not 27-33° BTDC, go to TEST GG - SPARK TIMING CHECK . If timing is 27-33° BTDC, go to KEY ON/ENGINE RUNNING (KOER) SELF-TEST .
