NOTICE: To prevent serious starter motor damage, release the ignition
switch immediately after the engine has started.
2. Turn on the ignition switch.
3. Wait for the engine system indicator lights on the instrument panel to go
out.
4. With foot off the accelerator pedal, start the engine.
5. If the engine does not start after 20 seconds, stop. Try again after waiting
about 60 seconds.
NOTICE: Do not increase engine speed if the oil pressure gauge indicates
no oil pressure. Shut down the engine within approximately ten seconds to
avoid engine damage. Check to determine the cause of the problem.
NOTE: Do not place the engine under full load until it reaches operating
temperature. Colder engine temperatures will cause the engine to preset
idle up to 900 rpm. Even at a high idle condition, you do not have to wait for
engine warm up and return to normal 600 rpm idle to drive the truck.
6. Monitor the oil pressure gauge immediately after starting the engine.
Running the Engine
While the engine is operating, monitor the battery charge indicator light, the oil
pressure, and avoid excessive idling.
Checking the Oil Pressure
Monitor the oil pressure as follows:
WARNING: HOT OIL
To avoid injury from hot oil, do not operate the engine with the
rocker cover(s) removed.
1. Observe the oil pressure gauge immediately after starting the engine. An oil
pressure gauge that registers pressure 14 psi (96 kPa) at idle speed and
normal operating temperature is a good indicator that all moving parts are
getting lubrication.
2. If no pressure is indicated within 10 to 15 seconds, stop the engine and
check the lubrication system at normal operating temperature.
3. The oil pressure should not drop below 55 psi (380 kPa) at 1800 rpm, at
normal operating temperature. If oil pressure does not fall within these
guidelines, check it with a manual gauge.
