Take pictures as you go, so you can remember how everything goes back together. If you aren't sure, it is a great idea to label the parts and connections to make reassembly much easier.
• Clean the area around the injectors: Use compressed air or a clean shop towel to remove any dirt or debris from around the injectors. This will prevent contamination from entering the fuel system when you remove the injectors.
• Apply penetrating oil: Generously spray penetrating oil around the base of the injectors and any bolts you plan to remove. Let it soak in for at least a few hours, or preferably overnight. This will help loosen things up and make removal easier.

Step 2: Disconnecting Fuel Lines and Electrical Connectors

• Disconnect the fuel lines: Carefully disconnect the fuel lines from the injectors. Be gentle, and use the appropriate fuel line removal tools if necessary. Cap the fuel lines to prevent fuel from spilling and to keep dirt out.
• Disconnect the electrical connectors: Unplug the electrical connectors from the injectors. These connectors can sometimes be tricky to remove, so take your time. You might need to press a release tab or use a small screwdriver to help.

Step 3: Removing the Injector Retaining Clamps/Bolts

• Loosen and remove the injector retaining bolts or clamps: Locate the bolts or clamps that hold the injectors in place. These can vary depending on your model. Use the correct socket or wrench to loosen and remove them. If the bolts are stuck, try applying more penetrating oil and letting it soak in. Don’t overtighten when reinstalling!

Step 4: Removing the Injectors

• Use the injector puller: Attach the injector puller to the injector. Follow the instructions for your specific puller. Gradually tighten the puller until the injector starts to come loose. Be patient, and don't force it. If the injector is stuck, try wiggling it gently while applying pressure with the puller.
• If the injector is really stuck: You might need to use a slide hammer or other specialized tools. If you’re struggling, it may be time to seek help from a professional. Sometimes, injectors get seized in place, and forcing them can cause damage.
