Operation, Tes
ting and Adjusting, “Air in Fuel -
Test .
5. Check that the
fuel lines are tight and secured
properly.
6. Check for fuel
supply lines that are restricted.
7. Check the fuel filters.
8. Visually check the fuel tank for fuel. The fuel
gauge may be faulty.
9. If the engine has a water separator, check for
water in the fuel.
10. Ensure that the fuel supply valve (if equipped) is
in the full OPEN position.
11. If the temperature is below 0 °C (32 °F), check
for solidified fuel (wax).
Engine Protection Device (if equipped)
1. Check if a war
ning lamp is ON.
2. Refer to Troubleshooting, “Indicator Lamp Circuit
-Test.
3. Repair any faults and ensure that the engine
protection
device is not in operation.
4. If the fault has not been eliminated refer to
“Electrica
l Connectors”.
Electrical Connectors
1. Check for correct installation of ECM connectors
at the following locations:,
J1/P1 ECM connector
J20/P20 Mac
hine interface connector
J401/P401 Speed/timing sensor connector
J100/P100 Intake manifold air temperature
sensor connector
J103/P103 Engine coolant temperature sensor
connector
J201/P201 Engine oil pressue sensor connector
J200/P200
Intake manifold pressure sensor
connector
P40 Fuel in
jection pump connector
2. Refer to Troubleshooting, “Electrical Connectors
- Inspect”.
3. Use the electronic service tool to check for
the following
logged diagnostic code: 253-02
“Incorrect ECM Software”. If this diagnostic code
is logged, proceed to Troubleshooting, “Electrical
Power Supply
Circuit - Test”.
4. Inspect the battery wires from the ECM back to
the battery c
ompartment. Refer to the Engine
Wiring Diagram. Inspect the wires and the power
relay. Check the power and ground connections to
the ECM. Refe
r to Troubleshooting, “Fuel Injection
Pump Circuit - Test” for more information.
5. Check the P40
VP30 fuel pump connector. Refer
to Troubleshooting, “Fuel Injection Pump Circuit
-Test.
6. Repair any faults and ensure that the faults have
been eliminated.
