Tracker 4WD V6-2.5L VIN 4 (2001)
Steps 11-19
The numbers below refer to the step numbers in the diagnostic table.
1. A Diagnostic System Check-Computers and Control Systems prompts the technician to complete some basic checks and to store the Freeze Frame
data on the scan tool if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the
scan tool for later reference.
3. This step checks to see if fuel system pressure is within specifications with the ignition ON and the fuel pump running. The fuel pump may be
operated with the scan tool Output Control feature when the fuel level is more than 20 percent and no DTCs are set.
4. This step checks the fuel pressure after the fuel pump stops. Approximately one minute after the fuel pump stops fuel pressure should remain
steady above 180 kPa (25 psi). The fuel pump may be operated with the scan tool Output Control feature when the fuel level is more than 20
percent and no DTCs are set.
5. The vehicle should start and run. At this step, adequate fuel pressure is available for the engine to operate. A vehicle that will not start may have
inoperable fuel injectors.
6. This step checks for normal fuel pressure when the engine is running. Fuel pressure that is not within the specified value indicates a possible fault
in the fuel pressure regulator.
8. This step checks for a faulty check valve in the fuel pump. Blocking (pinching) the fuel feed hose between the fuel pressure gage and the fuel
pump, immediately after the fuel pump stops, traps the fuel pressure between the fuel pressure regulator and the blocked section. If fuel pressure
now remains above the specified value, the fault is between the blocked section and the fuel tank. The fuel pump may be operated with the scan
tool Output Control feature when the fuel level is more than 20 percent and no DTCs are set.
9. This step checks for a faulty fuel pressure regulator. You may operate the fuel pump with the scan tool Output Control feature when the fuel level
