Fuel delivery is accomplished through a mechanical returnless fuel system (MRFS).  The fuel pump supplies the fuel injectors with pressurized fuel through the fuel rail.  Fuel pressure is controlled by the fuel pressure regulator which is mounted to the fuel pump support rods within the fuel tank.  The fuel tubes route the fuel from the fuel pump to the fuel rail.  The fuel filter cleans the fuel delivered from the fuel pump to the fuel rail. DIAGNOSTIC TESTS FUEL SYSTEM Special Tools Principles of Operation The fuel tank filler pipe assembly is used to refuel the vehicle. The fuel tank inlet check valve prevents spitback of fuel during and after refueling. The fuel tank stores the fuel. The fuel tank contains a Fuel Pump (FP) module. The FP module consists of a fuel level sender and a FP. The fuel level sender sends a signal to the fuel gauge informing the driver of how much fuel is in the fuel tank. The FP provides fuel to the fuel tubes which supply the fuel rail. During refueling, the fuel tank vents to the atmosphere through the vent and filler pipes, on vehicles without On-Board Refueling Vapor Recovery (ORVR) systems. In vehicles equipped with ORVR the fuel tank and filler pipe are designed so that when the vehicle is being refueled, fuel vapors in the fuel tank travel to the Evaporative Emission (EVAP) canister, which absorbs the fuel vapors and vents the pressure from the fuel tank during refueling. Inspection & Verification Illustration Tool Name Tool Number Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool NOTE: The following procedure diagnoses a slow to fill concern only. For all other concerns, refer to the Introduction - Gasoline Engines article. WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury. 2008 Ford Ranger 2008 GENERAL INFORMATION Fuel System - General Information - Ranger

1. Verify the customer concern by refueling the vehicle and observe the fuel fill rate. 2. Inspect to determine if any of the following mechanical concerns apply. VISUAL INSPECTION CHART WARNING: Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury. WARNING: When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage. Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instructions may result in serious personal injury. WARNING: Always disconnect the battery ground cable at the battery when working on an evaporative emission (EVAP) system or fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury. NOTE: Do not use incandescent lights when inspecting the fuel system. Use only fluorescent or LED lighting.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. 4. If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC). 5. If the scan tool does not communicate with the VCM:  check the VCM connection to the vehicle.  check the scan tool connection to the VCM.  refer to MODULE COMMUNICATIONS NETWORK article, No Power To The Scan Tool, to diagnose no power to the scan tool. 6. If the scan tool does not communicate with the vehicle:  verify the ignition key is in the ON position.  verify the scan tool operation with a known good vehicle.  refer to MODULE COMMUNICATIONS NETWORK article to diagnose no response from the PCM. 7. Carry out the network test.  If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK article.  If the network test passes, retrieve and record continuous memory DTCs. 8. Clear the continuous DTCs and carry out the self-test diagnostics for the EVAP system using the scan tool. 9. If the DTCs retrieved are related to the concern, go to EVAPORATIVE EMISSION SYSTEM DTC CHART . For PCM-related DTCs, refer to the POWERTRAIN DTC CHARTS AND DESCRIPTIONS - GASOLINE ENGINES article. For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article. 10. If no DTCs related to the concern are retrieved, go to Symptom Chart . DTC Chart EVAPORATIVE EMISSION SYSTEM DTC CHART NOTE: Make sure to use the latest scan tool software release. NOTE: The Vehicle Communication Module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.

Symptom Chart Symptom Chart Pinpoint Test Pinpoint Test A: Slow to Fill Normal Operation Under normal operation, fuel should flow at a steady rate through the fuel tank filler pipe into the fuel tank. As fuel enters the fuel tank air is vented through the filler pipe or the On-Board Refueling Vapor Recovery (ORVR) system. This pinpoint test is intended to diagnose the following:  Fuel tank filler pipe vent tube, if equipped  Fuel tank filler pipe  Evaporative Emission (EVAP) system  Fuel tank inlet check valve (part of the fuel tank)  Fuel level vent valve, if equipped (part of the Fuel Pump (FP) module) P0453 High Go to Pinpoint Test A .
