The spark advance system used on late-model vehicles adjust ignition timing using the ____.

Which of the following spark plug components causes electricity to jump the gap and return to the battery through the frame ground?

A cylinder that is not burning fuel on the power stroke is called a(n) ____ cylinder.

An engine cranks but will not start. A spark test shows a good, strong spark. Technician A says that the no-start problem could be caused by fouled spark plugs. Technician B says that a fuel system problem is the likely cause. Who is right?

The deposits on a properly burning spark plug should be ____.

While conducting a secondary wire resistance test, Technician A states that wire resistance should be approximately 12,000 ohms per foot. Technician B says that resistance should be about 50,000 ohms maximum for long spark plug cables. Who is right?

Timing advance is usually set several degrees before TDC.

The throttle position sensor reports engine rpm information to the vehicle’s computer.

Firing order of the cylinders is sometimes cast into the metal of the intake manifold.

High voltage is sent from the ignition coil to the spark plugs when current flow through the coil is broken, collapsing the magnetic field.

In a multiple discharge ignition system, each ignition coil is fired only once per power stroke.

Grasp a spark plug wire by the boot to disconnect it from the spark plug.

Direct ignition coils mount directly below each spark plug.

Bad insulation on secondary wires can easily be detected with an ohmmeter.

To start a spark plug in its hole, you should use a ratchet.

In late-model vehicles, ignition timing cannot be adjusted mechanically.

Radio suppression wires have about 1,000 ohms resistant per foot.

Primary windings in a coil usually consist of a few thousand turns of heavy wire

Technician A says if a system fails to alter dwell when it should, the ignition control module needs to be adjusted to correct dwell timing. Technician B says if a system fails to alter dwell when is should, the ignition control module has a problem and should be replace. Who is right?
