Follow these steps carefully
Work cold with no sparks or open flame. Relieve fuel pressure via the service port or the manual's procedure, then disconnect the negative battery cable. Wear gloves and eye protection; keep a class-B extinguisher nearby.
Remove the engine cover and any intake ducting blocking the fuel rail. Unplug each injector connector and label them by cylinder. Place towels under the rail to catch residual fuel.
Unbolt the fuel rail, lift it evenly with the injectors, and pull the faulty injector from the rail or head. Cap open ports immediately. Note O-ring positions on the nozzle and rail ends.
Compare the new injector to the old one. Install new O-rings lightly lubricated with clean engine oil or the specified assembly lube — never petroleum jelly on some designs. Transfer any retainer clips.
I've learned: petroleum jelly swells certain O-ring materials — use clean engine oil or the assembly lube the kit calls for. A swollen O-ring nicks on install and you'll be chasing a leak by Friday.
Seat the injector fully into the rail and head, reinstall the rail bolts evenly to the specified torque, and reconnect each connector until it clicks. Refit vacuum lines and covers.
Reconnect the battery and cycle the key to ON a few times (without starting) to pressurize the rail. Check every O-ring and rail feed for seepage before starting. Start up, confirm a smooth idle, and clear injector codes after a short drive.
Don't skip the key-cycle leak check. Fuel spraying onto a hot exhaust is how engine bays catch fire — I've seen a pinhole seep turn into a barbecue in seconds.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
