Question about 1993 Jeep Grand Cherokee
How to change the fuel injectors o-rings?
It is pretty standard on most vehicles it just depends on how many O-rings here is a picture an O ring on an injector. You can take a pick tool to remove the ring. The injectors should come out with some type of clip.
You can use the below just - the changing of the injectors. :)
Step1 Determine which fuel injector your Jeep Grand Cherokee will need. This depends not only on the make and model, but also the engine size. Models made from 1999 to 2004 may be equipped with a 2.7L OM647, 3.1L 531, 4.0L PowerTech, or 4.7L PowerTech engine. Models made after this date can have a 3.0L OM642, 3.7L PowerTech, 4.7L PowerTech, 5.7L Hemi or 6.1L Hemi. Step2 Relieve fuel system pressure and disconnect the negative battery cable with a socket wrench. Remove the air intake assembly and unplug the electrical connectors for the alternator. Step3 Detach the fuel lines from the fuel injectors. Remove the vacuum hoses and electrical connectors from the throttle body with a socket wrench. Step4 Unplug the electrical connectors for the fuel injectors, manifold absolute pressure sensor and intake air temperature sensor. Disconnect the ignition coils and mounting bolts for the fuel supply manifold with a socket wrench. This will allow you to remove the manifold with the injectors still attached. Discard the old O-rings. Step5 Install the new fuel injectors by reversing the removal procedure. Use a torque wrench to tighten the mounting bolts for the fuel supply manifold to 20 foot pounds. Step6 Start the engine and check for leaks.
