Engine Starting

wv 10.03.001
  1. Set the parking brake.
  2. Move the fuel shut-off valve handle to the RUN position.

    3. Notice: Protect the turbocharger during engine start-up by not opening the throttle or accelerating the engine above 1000 rpm until normal engine idle oil pressure registers on the gauge.

  3. For automatic transmissions, make sure that the transmission shift control is in Neutral (N), Park (P), or the Park Brake (PB) position.
  4. Turn the ignition switch to the START position. For the four-position ignition switch, see figure and figure for the three-position ignition switch. After the engine starts, release the key.
  5. Bring the engine up to operating speed gradually as it warms up and develops stable oil pressure.
    Notice:

    Do not crank the engine for more than 30 seconds at a time during any of the following procedures. Wait two minutes after each try to allow the starter to cool. Failure to do so could cause starter damage.

    Important: When the engine is started, it takes a short time to build up a lubricating oil film between the shafts and bearings, and between the pistons and cylinder walls. The oil pressure gauge indicates any drop in lubricating oil pressure within 15 seconds of engine startup.
