Fuel Rail Wiring Harness

I have a misfire in Cylinder 4. I changed the wires, coil pack, plugs, and injectors to find out it is the fuel rail wiring harness that plugs into the injectors. Problem is I cant find one. Anyone know where I can get one used for a cheap decent price?

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.

I have a 1996 nissan sunny fuel injected ... i have changed the plugs, injector rail, distributer, throttle body, and my engine is still misfiring can some one advise me please..


inspect the wiring for loose connections or bad wiring.

try adjusting first the distributor by turning it. It should adjust the timing. Other than that inspect the timing on the timing chain or the chain may have developed a slack.

The car has 28,000 on it. the motor is a 3.6, and scanner codes keep coming up as injector #6 and misfire on #6 cylinder. i have installed all new injectors, new coil on #6, and all new spark plugs. also...


Check for voltage at the plug, 12volts. Also check with a noid light when it is acting up. Wires tend to break right at the plug. check this to include pulling the wire and the plug. I've had them hanging together with just a strand or two and when it heats up it doesn't make a very good connection.

Trouble codes PO300, PO302, PO304,PO306,PO308


If you get
P0300
P0301
P0302
P0303
P0304
P0305
P0306
P0307
P0308

error codes and
you have an engine that misfires or runs rough, it can be the injector for that
cylinder or the coil pack. The P0300 code is a random misfire code and may or
may not be the above. All the other messages are for misfire of a particular
cylinder indicated by the last digit.

Test the coil pack by switching it to another spark plug and
see if the problem follows to that cylinder.

If that makes no difference, it is very likely the injector.
Disconnect the injector connector of the same cylinder and measure the
resistance. It should be 13.5 to 14.2 ohms at 70 degrees temp. It can be up to
16 ohms if the engine is hot. If you see a really high resistance or an open or
short then you can try to change the injector. If not, you can remove the fuel
rail on that side and switch the injector to another cylinder and see if the
problem follows to that cylinder.

You
need a 22mm wrench to remove the fuel pressure regulator. The other connections
are std. When all screws are removed, GENTLY wiggle the rail up and guide it
smoothly out. Don't put any sideward stress on the injector bodies.

Here is how to identify cylinders

Front of vehicle ^

1........2
3........4
5........6
7........8

All of the
injector connectors have a Black with red stripe wire. The corresponding other
wire color on the injector connector that matches with above are

red.........................white
green......................Red/black stripe
blue........................yellow
blue/red
stripe..........Red/white stripe

Has a 6.0 L with bad misfire under a load and is


Hi Brad,
I ran into the same problem your going thru,
swapped cylinder plug and wire ,and the scan kep telling me it was still seeing the problem on the same cylinder,
smoked it too,nothing made sense!
Until i took the whole fuel rail off carefully not to let the fuel run out all over the engine,Had a white rag folded up and handy,tilted the rail assembly and left the fuel run on the cloth,OMG! the rust that came out of there,
I pulled every injector out of the rail,cleaned the inside of the rail with air pressure and carb cleaner.
Its when I was checking the injectors that I found the culprit,the rust pieces had made it thru the injector but were trapped in the screen of the injector!
I hope this cures your.

Misfire on #2 cylinder reading code 1320


It's possible the fuel injector went bad on that cylinder.
My maxima did the same thing until I figured out it was the fuel injector the whole time.

If it's working properly, it should make a clicking noise. Best way to test it to unplug the wire connector to the injector and put 12v to it. It should click every time you appily 12 volts. ( warning, don't take the fuel injector off the fuel rail. GAS & SPARK don't mix)
