No, the fuel injector being plugged is likely not to affect the other 3 on the same side from getting fuel.

The fuel rail is really large in diameter compared to the orifice of the fuel injector.

If the fuel rail were plugged up, it would mean nothing would get through to the injectors, which generally does not happen.

    Any idea as to why one side seems to not be getting any fuel ?? I know it's getting a signal I can feel it clicking when I grab the plug in for the injectors and when I unplug one the idle stays the same however when I unplug one from the other side the idle becomes ruff .
    Any help ,thoughts or suggestions would be great thanks

    I see why you think that the fuel rail is pluged. What is the pressure of the fuel in the fuel rail?

Number 5 cylinder injector fires intermietenly.i replaced injector and injector plug.

It is impossible to answer your question without knowing the YEAR, MAKE, and MODEL of your vehicle.
That being said, either the fuel injection controller has failed, or there is a problem with the wire leading to the injector, or there is an obstruction in the fuel rail preventing fuel from reaching the injector. Use an circuit tester to see if the injector is regularly receiving a pulse. If it is not, you have a wiring issue or a bad ICU. If it is getting a regular pulse, you have an obstruction in the rail (or you still have a clogged injector).

How to install a fuel injector on a 2002 jeep liberty 3.7

so that mean the old one is all ready removed.?
or did you mean all steps in the fsm for INJECTOR.
the steps are the same on all EFI fuel rail injectors.
you could google that or you tube it or read the FSM.

hide call keys from step 2 on, or very bad things can happen.
(wife or kids no aware of danger)
ill just cover the (basics)
1: per FSM , depressurize the system, in can be at 60PSI
parked. so avoid fuel in eyes, or a fire. we do that first.
gain access to rail under failure. (RUF) (no barking)
2: remove injector X , wire plug. (failing)
3: then detach the injector rail clamps the both rails off as one....
injector are all now loose, to pull off.
4: add new seals to new injector, and install in reverse order.

that's it, only the gain access , varies,... mostly.

last depressure steps:
run engine,
remove fuel pump relay, engine stalls. key off, hide keys

next tje FSM words (just the OFF section)

  1. Remove fuel tank filler tube cap.
  2. Perform Fuel System Pressure Release Procedure.
  3. Remove negative battery cable at battery.
  4. Remove air duct at throttle body air box.
  5. Remove air box at throttle body.
  6. Disconnect fuel line latch clip and fuel line at fuel rail. A special tool will be necessary for fuel line disconnection.
  7. Remove necessary vacuum lines at throttle body.
  8. Disconnect electrical connectors at all 6 fuel injectors. Push red colored slider away from injector. While pushing slider, depress tab and remove connector from injector. The factory fuel injection wiring harness is numerically tagged (INJ 1, INJ 2, etc.) for injector position identification. If harness is not tagged, note wiring location before removal.
  9. Disconnect electrical connectors at throttle body sensors.
  10. Remove 6 ignition coils.
  11. Remove 4 fuel rail mounting bolts.
  12. Gently rock and pull left side of fuel rail until fuel injectors just start to clear machined holes in cylinder head. Gently rock and pull right side of rail until injectors just start to clear cylinder head holes. Repeat this procedure (left/right) until all injectors have cleared cylinder head holes.
  13. Remove fuel rail (with injectors attached) from engine.
end expert.
login and read all steps. that be best , then ask questions?

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.

Hello: Remove the fuel rail with the injectors attached and wires connected. Disable the ignition system. Have helper turn engine over, see if 3 & 4 injector are firing properly, some times the fuel rail gets trash in it and 3 & 4 do not get enough fuel. Remove the injectors from the fuel rail and see if the inlet to the injector has trash in it.

Removal & Installation

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.

Bobby, when you say you cleaned the injectors, do you mean you cleaned the tips that go into the intake, or the end that connects to the fuel rail? Pull your injection rail (fuel rail) and crank the engine over while it is out and see if fuel is spraying from the injectors in a cone shape spray, sounds like they are clogged, if you cannot remove the clogs by cleaning then they will have to be replaced, you can get them from a used engine or buy new ones. On the upper drivers side of your engine compartment you will find a diagnostic connector, there will be two ends close together, one has two rows of pins 4 pins in the top row and 2 pins in the bottom row, install a jumper wire between the 1st pin in the second row and the other plug, which has only one pin, turn on the key and count the check engine light flashes to retreive fault codes should all be two digit codes, let me know what codes you find and I can help.

Sounds like the idle air control valve. Fuel filter, plugs and wires, could also be the fuel injectors. Take it to Auto Zone they will diagnoses it for free. .

1998 mercury grand marquis 4.6 sparkplug change

un-plug the coil packs--injectors--pull wiring out of the way,and then unbolt the coil packs and pull them out,and use a 6 inch to 8 inch extension on a 3/8 drive rachet with a 5/8 plug socket...snug the plugs back in pretty good because the 4.6 and 5.4 are known to blow the plugs out and wreck the threads on the head.On the drivers side you may have to unbolt the fuel rail(2 bolts)and lift it up off from the injectors,make sure that you dont tear the 0 rings on the injectors and watch to see if some or any 0 rings comes off from the injectors and stays with the fuel rail..when putting the fuel rail back on the injectors,use a little motor oil and wipe it on all 0 rings to assist in going back together without tearing the 0 rings.
