Starting the Engine
NOTICE
Oil pressure should rise within 15 seconds after the
engine starts. Do not increase engine rpm until the oil
pressure gauge indicates normal. If oil pressure is
not indicated on the gauge within 15 seconds, DO
NOT operate the engine. STOP the engine, investi-
gate and correct the cause.
5. Do not apply a load to the engine for approximately
3 minutes. Run the engine until the water
temperature gauge has begun to rise. Check all
gauges during the warm-up period.
Note: Oil pressures and fuel pressures should be in
the normal range on the instrument panel. Engines
that are equipped with "WARNING" lamps do not
have an operating range. The "WARNING and
DIAGNOSTIC" lamp (if equipped) will flash while the
engine is cranking. The lamp should turn off after
sufficient engine oil pressure or fuel pressure is
achieved. Do not apply a load to the engine until the
oil pressure gauge indicates at least normal
pressure. Inspect the engine for leaks and/or unusual
noises.
If the engine is operated with a low load, the engine
will reach normal operating temperature sooner than
idling the engine with no load.
Starting Problems
An occasional starting problem may be caused by
one of the following items:
• Low battery charge
• Lack of fuel
• Problem with the wiring harness
If the engine fuel system has been run dry, fill the fuel
tank and prime the fuel system. Refer to the
Operation and Maintenance Manual, "Fuel System -
Prime" topic (Maintenance Section).
Problems with the Wiring Harness
Illustration 33
ECM Connector J2/P2
Locate the ECM. Check the connector in order to
ensure that the connector is secure. Lightly pull each
of the wires in the chassis harness.
1. Pull each wire with approximately 4.5 kg (10 lb) of
force. The wire should remain in the connector.
2. If a wire is loose, push the wire back into the
connector. Pull the wire again in order to ensure
that the wire is secure.
