A1 ATTEMPT TO CRANK ENGINE


NOTE
Note: Verify Inertia Fuel Shutoff (IFS) switch is set (button pushed in). Refer to Owner Guide for location.


Does engine crank?



YesNo
GO to A2.REFER to Group 03 in Service Manual.
A2 IDENTIFY TYPE OF NO START


NOTE
Note: The purpose of this Test Step is to identify intermittent No Starts in order to guide the technician to the proper repair procedure.


Does the vehicle start now?



YesNo
Vehicle is an intermittent No Start. GO to Pinpoint Test Step Z50and prepare to use the Ignition Intermittent Analyzer, DIST tool.Natural Gas Crown Victoria:
GO to A15.
3.0L Windstar:
GO to A3.
All Others:
GO to A4.
A3 CHECK MIL DURING CRANK
  • Key off.
  • Key on, observe Malfunction Indicator Lamp (MIL). MIL should be on, if not, go to Pinpoint Test
