  • The vehicles fuel lines are in very poor condition from external deterioration. Replacement lines will be required to prevent future leaks in the system as well as stop any current leaks. Install fuel pressure test equipment and relieve the fuel system pressure. Clean all the fuel line connections and areas surrounding the fuel lines unions and clamps before removal in order to avoid possible contamination of the fuel system. Disconnect the fuel feed and fuel return pipe quick-connect fittings in the engine compartment. Disconnect the evaporative emissions (EVAP) purge pipe at the EVAP canister purge valve. Remove the fuel and EVAP pipes from the retainers. Raise the vehicle. Disconnect the fuel return pipe quick-connect fitting. Disconnect the EVAP purge pipe at the EVAP canister. Disconnect the threaded fitting from the fuel filter outlet. Cap the fuel filter, the fuel feed pipe and the fuel return pipe as needed in order to stop any fuel leakage. Clean and evaporator and purge inlets to ensure there is no debris to contaminate the valve or canistor. Install the fuel and the EVAP pipe bundle. Remove the caps from the fuel filter, the fuel feed pipe, and the fuel return pipe. Connect the fuel return pipe quick-connect fitting. Connect the EVAP purge pipe at the EVAP canister. Connect the threaded fitting to the fuel filter outlet (The fuel filter is usually replaced while performing this repair if the vehicle's design permits). Use a back-up wrench in order to prevent the fuel filter from turning. Tighten the fuel filter fitting to 30 [n-m] (22 lb ft). Lower the vehicle and connect the fuel pipes at the fuel rail. Connect the EVAP purge pipe at the EVAP canister purge valve. Install the fuel and EVAP pipes into their retainers and verify proper clearance from the chassis components. Tighten the fuel tank filler pipe cap and reinstall access pressure port caps. Connect the negative battery cable and pressure test the fuel system to check for leaks.

  • Remove the four tires from the vehicle, and clean the wheel studs, hub flanges, and the rims centric. Check the vehicles braking system components for wear, remaining brake material, and signs of pending issues. Reinstall the tires onto the vehicle in their best suited locations based on overall wear, torquing all lugs to factory specification. Inflate all tires to the manufacturers suggested pressure, and visually assess the tread for abnormal wear which may indicate a need for a wheel alignment. Reset the vehicles tire pressure monitor sensor locations where required, using the factory approved TPMS (Tire Pressure Monitoring) system, scan tool. Road test the vehicle and confirm there is no abnormal handling characteristics following the rotation. Note: Some vehicles may have a slight drift following a tire rotation. This is due to a pattern that developes in some tires due to excessive time in one location. This condition should improve as the tread conforms to the new location / alignment angle. If drifting would not improve, sometimes an alignment or a cross rotation is required.

  • Install data scanner and engine analyzer. Run tests on the fuel, ignition, and computer control systems. Retrieve fault codes from the processors memory. Codes exist in the system for issues with the fuel tank pressure sensor. Perform all necessary pin point tests checking the wiring, grounds, relays, and related circuit components to isolate the problem to a failed fuel tank pressure sensor. Remove the vehicles tank, and remove the old pressure sensor assembly. Clean the terminal contacts as well as the sensor bore and found the sensor to be corroded. Clean the corrosion and reinstall the sensor assembly. Reinstall the removed components and reset the vehicles computer control system. Ordinarily we would have replaced the sensor while apart. Opting to repair the discovered damage saved the client $260.00 and following the repairs the system is operating glitch free. If the engine light returns for this code, further diagnostics may be required however it is unlikely.

Remove air filter element and clean the inside of the air inlet box. Reassemble air box and remove fuel lines at the filter assembly. Clean fuel line ends and replace o-rings, clips or sealing washers and install new fuel filter where applicable. Perform full injection system service using the Motor Vac System… The MotorVac Complete Fuel System Service is a revolutionary procedure that uses a specially designed machine that hooks directly to the vehicle. Utilizing a special detergent (which will not damage your vehicles sophisticated fuel system components) the equipment removes the dirt, varnish, and carbon deposits that normally build up on the intake valves, fuel injectors, and combustion surfaces. The air intake plenum, air charge, air bypass valve, and throttle body are also thoroughly cleaned during this process. In addition, oxygen sensors, and catalytic converters are cleaned reducing harmful exhaust emissions. All fuel system components are thoroughly tested as part of this service; Fuel pressure (static, and dynamic) regulator operation, leak down (at both injector assemblies and pump shuttle valve) and volume tests to verify that your fuel system is operating properly. Base idle adjustment is included where applicable. Install data scanner and run engine to operating temperature to verify that all computer controls are operating within parameters.
