With a car of its age, this is a common problem. If you have the fuel pressure tester and are not getting a reading when you have it screwed into the schrader valve, there is a good chance it is your fuel pump. Rarely do i get to see it be a relay or fuse. I hope this helps.

How to seat fuel injecters


Assuming the injectors are already installed in the fuel rail, put a little fuel on the injector seals, position the injector rail in front of the holes in the head.
Start from one end of the rail and work the first injector into its hole a little bit, but not all the way. then do the same for the second and third. Work them in a little at a time so the injectors dont come loose from the fuel rail.
Once you get all injectors completely into the holes, rotate each of them back and forth until the injector turns smoothly when you rotate it. Once an injector rotates smoothly its seated correctly. But only rotate them a small amount back and forth.
If the injectors are removed from the fuel rail, do it the same way. Just install them in the fuel rail first, then install the rail/injectors into the cylinder head.

How to remove fuel injector #3 diagram


Hi, the picture shown is the driver's side of the engine. Go to the passenger's side and remove the 2 similar screws holding the fuel rail. Disconnect all of the injector connectors on that side. Raise the rail up carefully until the injectors come free from the manifold. #3 is third back from the front of the engine. Twist and pull it out of the fitting on the rail. Oil the oring on the new injector and twist it in. Oil all of the lower orings and slip the injectors back into the manifold. Replace the 2 fuel rail bolts and reconnect the injectors. Please let me know if you have questions, and thanks for using FixYa.

Fuel injector reeplacement


you don`t say what motor is in this so here is a basic procedure, find the fuel rail where the fuel lines connect to at the intake manifold.disconnect the fuel lines(be carefull you could get gas in your eyes from fuel spray or start a fire due to hot engine)these lines have high pressure fuel in them.look at the fuel rails to see what all is in the way to remove them and remove interferance items.remove the bolts that hold the rails to the intake manifold,gently lift wiggle the fuel rails and you may have to pry up on the rails in places to get them to come out with the injectors attached the rails.you should make sure any debris is removed from around the injectors so no dirt falls into the injector holes before you remove.then you can remove the injector to rail lock clips and remove the injectors from the rails.clean areas were the injectors will be going apply either gas or silicone on the injector O rings then install injectors to rail install lock clips and reassemble.replace all the O rings as they get dried out brittle and crack or split.re-install removed components start car and check for fuel leaks.

I have fuel leaking from the fuel rail at the 2nd injector from the front. The leak seems to be coming from where the metal of the fuel rail conects to the plastic....


Maybe an O-ring is leaking. Try a new injector that comes with an o-ring to be sure it's not the injector itself.

After removing the fuel injectors and rail to remove the manifold, how do you reinstall the fuel injectors?


the same way you took it apart. put a little grease around the rubber seals so they will slide in easier. just tap on the fuel rail while lightly tapping it into place.
