MOTOR AGE GARAGE TEST 482 12/031985 Ford F-150 Pickup: Hard start after heat soak.1. In most fuel injected applications, clear flood mode is attained
by:
A. Removing the fuel pump fuse.
B. Removing the fuel injector fuse.
C. Holding the throttle wide open.
D. Disabling the fuel system with a scan tool.2. During a heat soak period the engine temperature will:
A. Rise.
B. Fall.
C. Remain the same.
D. Rise very briefly then fall.3. To properly check the voltage drop across a connector you should:
A. Place the voltmeter leads on either side of the connector with the system under load.
B. Place the voltmeter leads on either side of the connector with the system off.
C. Place one voltmeter lead on battery positive and the other lead on the connector.
D. Place one voltmeter lead on battery negative and the other lead on the connector.4. To check the fuel pump check valve for leak-down you should:
A. Tee the gauge into the fuel line anywhere on the pressure side of the system.
B. Connect the gauge with no tee to the pressure side of the system before the fuel rail.
C. Connect the gauge with no tee after the fuel rail.
D. Tee the gauge into the return side of the system.5. To check the fuel injectors for leak-down you should:
A. Connect the gauge with no tee to the outlet side of the fuel rail.
B. Make sure that the fuel pump check valve does not leak down.
C. Make sure that the fuel pressure regulator does not leak down.
D. All of the above.6. Technician A says that a leaking fuel pressure regulator diaphragm will cause a rich fuel mixture. Technician B says that a leaking fuel pressure regulator diaphragm will have fuel in the regulator vacuum supply tube. Who is right?
A. Technician A.
B. Technician B.
C. Both A and B.
D. Neither A nor B.7. Fuel pump amperage draw will be affected by:
A. Voltage supply.
B. Brush contact.
C. A dirty pump ground connection.
D. All the above.8. Fuel pump speed can be determined with an amperage probe and a lab scope if you: A. Know the number of commutator bars and can see a
