2001 GMC Jimmy Parts Questions & Experts Answers

• Q: How to replace a fuel injector on 2001 GMC Jimmy?

  A: Before starting the Fuel Injector replacement process begin by disconnecting the negative Battery Cable followed by fuel system pressure relief. The first step requires removal of both the upper intake manifold assembly together with the fuel meter body assembly. Work to remove the Fuel Injector retainer assembly along with its lock nuts yet ensure the electrical terminals and fuelscope remain undamaged because the injector acts as a whole assembly and dissolving it with cleaning solvents is not permitted. You need a small tip punch to push the terminals downward when the poppet nozzle tube is positioned downward to remove the injector. New injector o-ring seals need cleaning engine oil for lubrication before placing them onto the injector assembly structure. The Fuel Injector assembly should be inserted into the fuel meter body injector socket while using the injector assembly retainer and the injector retainer lock nuts . Tighten these lock nuts to 3.0 n.m (27 lb in) torque setting. Install the fuel meter body assembly as well as the upper intake manifold assembly to completion while securely tightening the fuel filler cap and reestablishing the negative Battery Cable. The inspection for leaks includes activating the ignition switch for two seconds then waiting ten seconds for turning it off and back on to verify if fuel leaks occur.
