What You'll Learn
Remove the gas cap and drain the rails
To remove the fuel injectors from your 1987 Camaro, you'll first need to remove the gas cap and drain the rails. Here's a detailed guide on how to do this:
Before beginning any work on your fuel injectors, it is important to take necessary safety precautions. Ensure you are wearing appropriate protective gear, including eye protection and gloves, and have a fire extinguisher nearby. Work in a well-ventilated area to avoid inhaling fumes. Start by locating the fuel rail, which runs along the top of the engine. To access it, you may need to remove the plastic shroud covering the engine, which is typically secured with small screws or clips. Be cautious as you work, as the fuel system is under pressure and there may be residual fuel that could spill.
Now, remove the gas cap to relieve the pressure in the fuel system. This will allow you to safely drain the fuel rails. Locate the Schrader valve, usually found near the fuel rail, and use a screwdriver to release the pressure. Alternatively, you can evacuate the fuel system pressure by pulling the fuel pump relay and running the car until it doesn't start. Make sure to also disconnect the negative battery cable before proceeding.
Once the pressure is released, you can proceed to drain the fuel rails. Place a suitable container under the fuel rail to catch the draining fuel. Be cautious as you work to avoid any spills or leaks, as they can be dangerous. If there is a significant amount of fuel in the rail, you may want to consider using a siphon to help with the draining process. Ensure that you properly dispose of the drained fuel according to local regulations.
After draining the fuel rails, you can move on to the next step of removing the fuel injectors. It is important to work carefully and methodically when dealing with the fuel system to ensure your safety and avoid any damage to the vehicle. Remember to refer to your Camaro's manual for additional information specific to your model, and if you have any concerns or uncertainties, seek advice from a qualified mechanic.

Remove the bolts holding the fuel rail and the fuel injector clips
To remove the bolts holding the fuel rail and the fuel injector clips from your 1987 Camaro, you will first need to relieve the fuel system pressure. This can be done by evacuating the fuel pressure, as suggested in the user manual, or by sticking a screwdriver in the Schrader valve and releasing the pressure. Be sure to also remove the gas cap and drain the rails with the Schrader valve.
Once the pressure is relieved, you can then remove the bolts. Make sure all the bolts are out before attempting to remove the rail, as it might take a good bit of force. You can use a pry bar to help remove the rail, but be careful not to bend or break anything. It is also recommended to spray some silicone spray or WD-40 where the injectors go into the bored holes to help loosen them.
After the bolts are removed, you can then remove the fuel rail and fuel injector clips. The clips are what hold the injectors in place, so be sure to remove them carefully. There may also be a metal retainer clip that goes around the outside of the injector, which you can pull off to release the injector.
In addition, it is important to inspect the O-rings for any damage and replace them as necessary. When reinstalling the injectors, lubricate the new O-ring seals with clean engine oil and install them on the injectors. Finally, install the retainer clip onto the injectors and rotate it to the lock position.

Twist and wiggle the injector while pulling it from the rail
When removing fuel injectors from a fuel rail, it is important to first release the wiring harness clips at the back with a flat screwdriver. These are click lock clips and are easy to undo. Once this is done, you can then twist and wiggle the injector while pulling it from the rail. This step requires some force, so be prepared to pull with a good amount of strength. The twisting and wiggling motion helps to loosen the injector from the rail, as the o-rings tend to stick and make it difficult to remove.
It is recommended to inspect the o-rings for any damage and replace them if necessary. Lubricating the o-rings with a smear of synthetic motor oil on both the top and bottom during assembly can also help with the removal process. By twisting and wiggling the injector while pulling, you can free it from the rail and complete the removal process.
In some cases, there may be metal clips that need to be removed before the injector can be pulled out. These clips go around the outside of the injector and the bung it goes into. Make sure to slide the clip in the direction to remove it from the injector and lift up the little prong so it clears the machined part on the bottom of the fuel rail. Once the clip is removed, you can then twist and wiggle the injector to pull it out.
It is important to note that this process may vary slightly depending on the specific make and model of your Camaro. Always refer to a trusted repair manual or seek the advice of a qualified mechanic if you are unsure about any steps or procedures.
