How to replace the fuel injectors on GMC Sierra 1500?

The air cleaner outlet duct must be removed carefully before the replacement can start. Begin the fuel system pressure relief operation with ch-48027 or perform it without the tool then remove the engine wiring harness bracket nut. Next disconnect the electrical connectors from the evap purge solenoid, generator, map sensor, ignition coil main electrical connector and the fuel injectors. First mark each connector for later assembly before you move the cpa retainer with one click and press the tab to disconnect the Fuel Injector electrical connectors. Above the electronic throttle control device and Fuel Injector suite disconnect the electrical connectors while using the standard marking procedures. Uninstall those engine wiring harness clips which support the generator battery jumper cable and ignition coil bracket stud . Remove negative battery cable stud and terminals (2 and 3) from the Cylinder Head. First disconnect the wiring harness clip bolt from the generator bracket then place the harness aside while also removing the chassis fuel feed pipe quick connect fitting from the Fuel Rail. Lift out the evap purge solenoid from its position on the Fuel Rail by removing the bolts after unhitching evap tube fasteners at both the intake manifold and evap purge solenoid. Detach the Fuel Rail assembly while taking care not to harm either the injector electrical connector terminals or spray tips and apply caps over each fitting to stop any contamination. Evacuate all injectors from their bores while lifting the Fuel Rail in an even manner after cleaning it as needed. The installation of fuel injectors requires removing their retainers in combination with injectors and discarding the o-ring seals that sit at positions 2 and 4. First clean the engine oil to lubricate the new o-ring seals before attaching them to the injectors and installing the injectors into the Fuel Rail with retainers in place. After applying lubrication to the lower o-ring seals install the Fuel Rail onto the intake manifold while applying firm downward pressure until it reaches a complete position. First tighten 10 nm (89 lb in) Fuel Rail bolts before reinstalling the evap tube along with purge solenoid and making quick connect fittings to the evap canister and intake manifold. First reattach the Fuel Rail to the chassis feed pipe. After that, install the pcv hose before gathering all engine wiring harnesses over the engine. Take the generator bracket as the installation site for the wiring harness clip while tightening its clip bolt to 9 nm (80 lb in). Reinstall the negative battery cable stud on the right Cylinder Head unit while fastening it with 25 nm torque setting (18 lb ft). One should first reconnect the ignition coil main electrical connector then install the cpa retainer. Seed the electronic throttle control and Fuel Injector electrical connectors before tightening the cpa retainer. Fasten the engine wiring harness bracket nut with 5 nm (44 lb in) torque. After that, connect the MAP Sensor , generator and evap purge solenoid connectors followed by engine harness bracket assembly. Turn the ignition to on then off starting with two seconds of on time followed by ten seconds of off time before repeating the on step to check for any fluid leakage. Inspect for any leaks. Reinstall the air cleaner outlet duct at the end of the installation procedure.
