Actually you can seat the injectors first then place the rail on top of it ,, or you can place the injectors in the rail,and place the entire thing in.
ps use a bit of motor oil to hold the plastic raisers for the injectors in place.

What is a fuel rail


A fuel rail, technically known as a common rail, is essentially a pipe (usually resembling a rail) used to deliver fuel to individual fuel injectors on internal combustion engines. It is designed to have a pocket or seat for each injector as well as an inlet for a fuel supply. Some fuel rails also incorporate an attached fuel pressure regulator. Fuel rails are used on engines with multi-point fuel injection systems, although some multi-point systems use a fuel distributor with individual pipes or tubes to feed each injector.

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.

Misfire on cylender 1 dealer says it is fuel injector 1, could be pluged up or need replaced. dont have money for dealer to fix. how hard is it to fix myself?


Actually not that hard, but it does require some tools. Normally you will find the fuel rail fastened down in some manner on top of the fuel injectors along that side of the engine. First step is to find the relief valve (looks like a tire valve), be warned that fuel will be under some pressure when you push this valve, do not do this on a hot or warm engine and put a rag around the valve to catch excess fuel.

Remove the fuel rail, then carefully unplug the wiring connector on the # 1 cylinder fuel injector. The injector should come out with a good firm tug, make sure that any O-ring has not been left inside the injector seating area. Place a single drop of oil on the new injector's O-ring and push it into place. Replace the electrical connector, then the fuel rail. Turn on the ignition, but do not start yet - check for any fuel leaks. If none, then start the engine and you should be good to go.

Removal & Installation

8205896.gif
Exploded view of the fuel rail and injector mounting


Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
  1. Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
  2. Properly relieve the fuel system pressure and disconnect the negative battery cable.
  3. Remove the air intake duct, as necessary for access.
  4. Tag and disengage the fuel injector electrical connectors.
  5. Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
  6. Loosen and remove the fuel rail retaining bolts.
  7. If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
  8. Carefully lift the fuel rail assembly and fuel injectors from the intake.
  9. Carefully release and separate the fuel injectors from the rail assembly.
  10. Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
To install:
  1. Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
  2. Install the injectors to the fuel rail assembly.
  3. Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
  4. Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
  5. If removed, connect the fuel lines to the rail assembly and secure the fittings.
  6. Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
  7. Engage the injector electrical connectors.
  8. Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
  9. Install the air intake duct.

Replacing fuel injector on jeep 2.5


Disconnect your Battery.
Remove your air intake and filter housing all the way to the throttle body. Then use a shop rag and release te pressure in the fuel system by the valve on the fuel rail. use the rag to absorb the fuel as it sprays out the fuel rail.
then you unsrew the 2 bolts holing the rail in place.
Then you pry the rail away from the manifold with a flat head.
being careful not to loose any of your injector seals.
when done clean both your injector seats and the rail seats.
use some assembly lube or shop grease to lubricate all of your injector seals upper and lower seals.
remount all parts as you dismounted.
reconnect your battery cylce the ignition key 4-5 times before starting the egine, and check for leaks. if there is no leak then go ahed and start your engine.
