Disconnect the battery
Disconnecting the battery is an important step when removing the fuel injector line on a 98 S10. This is a safety precaution to prevent any accidental sparks or electrical issues during the process. Here is a step-by-step guide on how to safely disconnect the battery:
First, locate the battery in your S10. It is usually found in the engine bay, typically near the front of the vehicle. Open the hood and identify the battery by looking for a rectangular black case with two terminals, marked positive (+) and negative (-).
Once you have located the battery, the next step is to disconnect the battery cables. Before beginning this process, it is essential to ensure that the vehicle is turned off, and no electrical accessories are running. Start by loosening the nut or bolt that secures the negative cable to the battery terminal using an appropriate-sized wrench or socket. Be careful not to touch any metal parts of the battery or vehicle with metal tools or jewelry. Once loose, carefully detach the cable from the terminal. You may need to wiggle it gently to separate it. Set the cable aside, ensuring it does not touch any metal parts of the vehicle.
Next, repeat this process for the positive cable. Loosen the nut or bolt securing the positive cable to the battery terminal and then detach the cable. Again, be cautious to avoid any contact with metal surfaces. With both cables disconnected, you have successfully disconnected the battery.
It is good practice to clean the battery terminals while they are exposed. You can use a mixture of water and baking soda, along with a wire brush, to remove any corrosion or buildup. This helps improve conductivity and prevents electrical issues.
Remember to exercise caution when working with the battery, and always follow the vehicle's specific guidelines and safety procedures. Refer to your S10 owner's manual for detailed instructions on battery disconnection and reconnection.

Remove the fuel rail attaching bolts
To remove the fuel rail attaching bolts, you must first relieve the fuel system pressure. This can be done by running the truck without the fuel pump relay until it shuts off, releasing the pressure. You can also release the pressure with a Schrader valve located at the rear of the fuel rail. Next, disconnect the negative battery cable. Then, remove the intake assembly, starting with the throttle body and loosening all four hose clamps down to the air filter. Don't forget the one under the upper radiator hose on the left side.
Once the intake assembly is removed, you can access the fuel rail attaching bolts. Use the appropriate tool to loosen and remove these bolts. Be prepared for them to be challenging to loosen, as fuel rail attaching bolts can be stover nuts or distorted thread lock nuts, which typically require a decent amount of effort to remove.
After removing the fuel rail attaching bolts, you can carefully pull on the fuel rail until you hear the injectors pop out. Be cautious during this step, as you don't want to damage the injectors unless you are replacing them. It is crucial to be gentle and avoid snagging the injectors on anything.
If you are replacing the injectors, you can release each one by unplugging the wire connected to it. To do this, pull up on the blue clip until it hits the black tab, then push on the tab to release it. Finally, release the clip holding the injector to the fuel rail with a screwdriver. Be cautious, as the clip can fly off, so ensure it is pointed away from you when you pop it off.

Lift the fuel rail assembly
To lift the fuel rail assembly, you must first relieve the fuel system pressure. Refer to your car manual's Fuel Pressure Relief Procedure for this. Next, disconnect the negative battery cable. Then, remove the intake manifold assembly. Now, remove the fuel injector electrical connectors by pushing in the wire connector clip and pulling the electrical connector away from the fuel injector. Remove the fuel feed inlet pipe at the rail. Unscrew the fuel rail attaching bolts. Finally, carefully lift the fuel rail assembly from the cylinder.
It is important to note that you should be careful not to damage the injectors when lifting the fuel rail assembly. If you are replacing the injectors, you must still be cautious to avoid any damage. Once the fuel rail is unbolted, carefully pull on the fuel rail until you hear the injectors pop out. You can then slide the assembly out from the front of the intake.
To release each injector, unplug the wire to each one. Do this by pulling up on the blue clip until it hits the black tab, and then push on the tab to release it. Be cautious, as the clip holding the injector to the fuel rail can go flying when you release it. Point it away from you when popping it off.
Installation of the fuel rail assembly is the same as the removal process, but with a few extra steps. Apply a small amount of Vaseline to the injector seals and the intake hose that goes under the upper radiator hose to make everything slide together more smoothly.
