    Q:
    How to replace the Fuel Injection Fuel Rail Assembly on Chevrolet Tahoe? Posted by Customer
    A:
    The air cleaner outlet duct must be removed first before starting the fuel injection Fuel Rail assembly replacement. The correct technique should be used to release pressure from the fuel system. Proceed by unscrewing the engine wiring harness bracket nut followed by disconnecting the engine wiring harness electrical connectors to separate the evap purge solenoid along with MAP Sensor and ignition coil main electrical connector and fuel injectors while taking proper marks for reassembly. The ignition coil bracket stud requires removal of its engine wiring harness clip before moving the heater hose bracket by removing its retaining nut. The chassis fuel feed pipe quick connect fitting as well as the evap tube quick connect fittings at both the Intake Manifold and evap canister purge solenoid need removal. After disconnecting the evap canister purge solenoid retainer from the Fuel Rail you should remove the Fuel Rail bolts and carefully lift the assembly to prevent damage to injector electrical terminals and spray tips. Clean the Fuel Rail as needed while you remove both Fuel Injector retainers and fuel injectors which require replacing the o-ring seals at the top and bottom positions (2 and 4). Apply engine oil to new Fuel Injector o-ring seals before mounting them on the injectors before inserting the fuel injectors into the Fuel Rail with retainer installation. Install the Fuel Rail on the Intake Manifold until it rests in its proper position and tighten the Fuel Rail bolts to 10 nm before removing installation. Reconnect the evap tube and purge solenoid and the evap canister purge solenoid at its chassis tube quick connect fitting along with the Intake Manifold quick connect fitting. The technician reconnects the Fuel Rail quick connect fitting from the chassis fuel feed pipe while installing the pcv hose before gathering engine wiring harness branches over the engine. Follow these steps to install the engine wiring harness clip bolt by tightening it to 9 nm and position the heater hose bracket before tightening its nut to 9 nm. The engine wiring harness requires proper connection of electrical connectors to the ignition coil main electrical connector and electronic throttle control and fuel injectors and the cpa retainers must lock into place. Complete the procedure with a connecting step that involves your negative Battery Cable and a leak check when turning ignition on then off followed by the duct-based reinstallation of the air cleaner outlet.

    Q:
    How to replace the fuel rail assembly on Chevrolet Trailblazer? Posted by Customer
    A:
    You need to use an appropriate method to first reduce the pressure in the fuel system before starting replacement of the Fuel Rail assembly. First locate the Fuel Rail then disconnect its fuel feed pipe before taking out the Intake Manifold. Engine cleaners like gm x-30a or equivalent should be used to clean the Fuel Rail assembly and cylinder head by following spray type cleaning instructions without subjecting the Fuel Rail to soaking with liquid solvent. Cut off the Fuel Injector harness in-line connector from the engine wire harness then take it away from the rocker cover. Remove the Fuel Rail attaching bolts first and extract the Fuel Rail assembly with gentle procedure to safeguard the injector electrical terminals and spray tips by capping the fittings and plugging the holes to stop contamination. Eliminate and dispose of the injector lower o-ring seals from each component. Continue the Fuel Rail installation if replacement is not required. The installation begins with removing the Fuel Injector wire harness from the Fuel Rail before removing the fuel injectors. During assembly process first attach the Fuel Injector harness to the Fuel Rail before installing the fuel injectors. New lower injector o-ring seals require clean engine oil lubrication before their installation on spray tips of each injector as part of the Fuel Rail assembly installation process. After applying threadlock gm p/n 12345382 (Canadian P/N 10953489) or equivalent to a 5 mm (0.2 in) wide area of the Fuel Rail bolt threads you should install the bolts with a torque setting of 10 nm (89 lb in). Stop by attaching the Fuel Injector harness in-line connector to engine wire harness near the rocker cover before joining the fuel feed pipe with the Fuel Rail followed by Fuel Injector electrical connectors. Connect the Intake Manifold while also restoring the negative Battery Cable. Turn on the ignition while the engine remains off for two seconds before turning off the ignition for ten seconds. Finally check for fuel leaks while once again turning on the ignition with the engine off.

    Q:
    How to replace the Fuel Injection Fuel Rail Assembly on GMC Yukon? Posted by Customer
    A:
    The procedure for fuel injection Fuel Rail assembly replacement starts by first eliminating air cleaner outlet duct and then completing fuel system pressure relief in two ways using ch 48027 or without it. The first step involves removing the engine wiring harness bracket nut followed by disconnecting electrical connectors from evap purge solenoid as well as generator and MAP Sensor and electronic throttle control and ignition coil main electrical connector. Unplug all Fuel Injector electrical connectors before marking them for reinstallation and then take out the cpa retainer to disconnect additional connectors. Disassemble the cylinder head by removing terminal (2 and 3), negative battery cable stud, clips (4 and 6) and engine wiring harness from its location. Start by removing the bolt of the engine wiring harness clip and place the harness in a safe position aside. Remove the connections of the pcv hose alongside the chassis fuel feed pipe and evap tubes from their locations at the Intake Manifold and evap canister purge solenoid. First disengage the retainer of the evap canister purge solenoid then remove the Fuel Rail bolts. To avoid touching the injector electrical connectors or spray tips the technician should carefully take out the Fuel Rail assembly while using caps to protect all exposed fittings from contamination. Spray engine cleaner on the Fuel Rail while cleaning it before removing the Fuel Rail assembly evenly until completion. Get rid of the old Fuel Injector O-Ring seals (2 and 4) that should be discarded. Insert new o-ring seals onto the fuel injectors while applying clean engine oil to the seals before installing the fuel injectors with their retainers. Fully push the Fuel Rail toward the Intake Manifold until all injectors are properly positioned before tightening the Fuel Rail bolts to 10 n.m (89 lb in). Reinstall the evap tube after which you should add the purge solenoid and connect the evap tube fittings and the chassis fuel feed pipe. After repositioning the pcv hose install the engine wiring harness and tighten its clip bolt to 9 n.m (80 lb in). Tighten the terminal and stud connecting the negative battery cable to the cylinder head until they reach 25 n.m (18 lb ft). After connecting the ignition coil main electrical connector you must install the cpa retainer. When connecting the electronic throttle control and Fuel Injector connectors ensure that their cpa retainers remain properly in place. Connect the MAP Sensor to the generator while installing the evap purge solenoid and secure the engine wiring harness bracket nut at 5 n.m torque (44 lb in). Complete the procedure by reversing battery cable connection and leak check per instructions before reattaching the air cleaner outlet duct.
