How to replace fule injectors in your car?

1.The metal rod over the fuel injectors is the fuel rail. Use the socket and ratchet to remove the bolts and brackets holding the fuel rail in place. Depending on the model, some engines will need the fuel line disconnected from the fuel rail in order to move the rail.

A :Make sure the engine is cold enough to touch. Disconnect the battery.

B :Remove plastic engine covers using appropriate socket. Set covers aside.

 

2.First, disconnect the main fuel line at the end of the rail. There may be an additional line at the other end, so remove that one, too. The fuel rail is held in place by screws or bolts, depending on your car's setup. Remove these screws or bolts. If your wiring travels over the top of the rail, see the next step to disconnect the wiring first. With everything disconnected from the rail, pull it away from the fuel injectors. Most fuel rails are just pressed onto the injector tops, once you've removed the hold down screws or bolts it should pull away, with a little soomph.

 

 

3.Using a small standard screwdriver or pick remove the retainer clip from the fuel injector and work the injector from the rail. Keep a shop towel handy to catch excess fuel while removing the injector.

Inspect the old fuel injector making sure the sealing O rings are accounted for.Match the new injector to the old unit, some injector replacements can look a little different which is normal.

 

4.Use clean engine oil to lube the O ring seals preventing seal damage during reassembly.

 

5.Push the new injector into the fuel rail and reinsert the trainer clip and tighten down the fuel rail.

 

6.After the job is complete start the engine while using a flashlight to check for leaks to ensure the job was done correctly.
