Visual Inspection

1. All diagnostic procedures must start with a thorough visual inspection of the vehicle.
2. Start the visual inspection with the examination of the electrical connections of the components found in Locations/Components. The connectors and terminals must be locked together. Look for terminals that are pushed out, loose or corroded. Make sure that wiring between each connector is not pinched behind any screws or bolts, or rubbing on drive belts, sharp metal, or exhaust systems.
3. Look for any added accessories that may affect the normal operation of the MPI system (alarms, kill switches, etc..).
4. All hose and vacuum line connections must be secure and hoses must not be pinched, collapsed or cut.
5. Intake hoses and the air cleaner housing must be in place and secure for normal operation and testing.

NOTE: This is of particular importance, since this vehicle has an airflow sensor.

6. The battery must be fully charged.
