How do i remove the fuel injector plugs - 2008 Kia Sorento 3.3

Silverado 1500 or 2500 or 3500 or HD? no pickup told
not told the job you are doing>??
remove them all ,or scope them or just what, no job told
no end goal or task told. sorry can guess it.

like most V6/8 now , it is a sandwich.
the service manual covers all,l buy it rent it.?
toss dice and land on 1500
the rail on this engine, fuel rail like all , intake manifold injectors used;. all injector held down by both rails. left and right
now the steps to off them if is the job,
pull the isolator seen photo 1, far below.
1: pull left rail and right rail
Remove and discard the fuel injector retainer clips by installing EN-51097 injector retaining clip installer and spreading both sides of the clip evenly.
Always use NEW fuel injector collars supplied with injector when installing the new injector. If reinstalling the injector, it is not necessary to remove the collars unless the collars are being replaced.
Replace the injector seals as needed. Refer to Fuel Rail and Injectors Cleaning and Inspection.
Note
Inspect the injectors to be sure that they are clean and free of debris prior to installation. Do NOT lubricate the injector seals. Rebuild the fuel injectors whenever the injector has been removed from the fuel injector rail.


now I will past the other page rails off per the manual read to you.
just bank 1, i am to lazy to post both
step 1 rail off bank1.
Note
Inspect the injectors to be sure that they are clean and free of debris prior to installation. Do NOT lubricate the injector seals. Rebuild the fuel injectors whenever the injector has been removed from the fuel injector rail.

1. Remove the fuel pump insulator. Fuel Pump Insulator Replacement
2. Remove the fuel injector intermediate pipe position?1. Fuel Feed Intermediate Pipe Replacement - Position 1
3. Clean the cylinder head pocket around the injectors of any dirt or buildup.
4. Disconnect the electrical wiring harness connectors from the fuel rail.
5. the fuel rail fasteners are retained in the fuel rail by keepers and may be difficult to remove.Remove the fuel rail fasteners?(1) securing the injector rail?(2).
   Install two sets of EN-49248 remover?(3).
6. Install one remover in each of the fuel rail fastener bores.
7. Remove by turning each section of the EN-49248 remover an even amount to pull the fuel rail and injectors out evenly.
8. CAUTION
9. Remove the fuel rail assembly carefully in order to prevent damage to the injector electrical connector terminals and the injector spray tips. Support the fuel rail after the fuel rail is removed in order to avoid damaging the fuel rail components.
10. Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering open pipes and passages.
11. 1. Simultaneously lift both ends of the fuel rail?(2) and remove the fuel rail assembly from the cylinder head.
12. Remove and DISCARD the fuel injector seals.
13. Some vehicles were not originally equipped with fuel injector dust seals. A NEW seal must be installed when the injectors are removed.
    Remove and DISCARD the fuel injector dust seal (1).
14. NOTE
    Note
    Whenever the fuel injectors are removed from the cylinder head or fuel rail, they will need to be rebuilt. Fuel Rail and Injectors Cleaning and Inspection
    If replacing the fuel injection fuel rail, remove the fuel injectors. Fuel Injector Replacement

Installation Procedure, skipped me. the service manual lists 4 tools
per

Special Tools

1. EN-49248 Injector Rail Assembly Remover
2. EN-51105-1 Injector Seal Installer and Sizer
3. EN-49245-3 Fuel Injection Seal Installer Sizer
4. EN-49245-4 Fuel Injection Seal Installer Sizer

this is first. pull the isolator.

this one step is the GET TO ANSWEREd
Injector work 10x more complex and special tools needed x4

Check if the injector is spraying fuel. Remove 1 spark plug and crank. There should be some fuel smell from the plug hole. Or pull out the injectors and the fuel rail and place each injector into a small bottle. if you crank for 1 minute you should see fuel collected in the bottle.
if there is none, the immobilizer maybe stopping the ECU from opening the injectors.

Sounds like you have either a shorted fuel pump driver ground or a sticking fuel injector or injectors. Remove the injector electrical plugs and see if it still flood if it does then then one or more injectors are defective, if not then the engine wiring harness is grounded to one or more injectors or the PCM (powertrain control module) is defective. Remove the spark plugs to ID which cylinder is defective, disable the ignition system when you do this or the gas squirting out the spark plug hole can ignite (been there)

only remove fuel injectors after you have properly marked all the fuel pipes for what cylinder to go to (it matters!!) also carefully bleed off high pressure fuel from lines before removing them all the way (watch your eyes!!) use only a six sided socket to remove fuel injectors or you may damage them , try to avoid using an "IMpact" gun to remove , and allways reinstall with using a torque wrench to assure proper tightness , make sure you get fuel lines back exactly on new injectors exactly as you took them off , its also a good idea to replace glow plugs if equipped at same time

Check out the fuel pressure and fuel flow. There is a filter basket in the injector ,just in side the where the fuel line connects ,it can be removed with a small self taping screw , take care not to damage it. also check the injector spray and volume of fuel injected over a given time.

check you have pushed down the rubber boot that covers your plugs..to remove your injectors care needed .due to risk of fire. put cloths under your fuel rail.take off your battery lead.remove the bolts on the fuel rail.pull off the clips holding the injectors to your fuel rail. now pull up the rail.your injectors should lift off at the same time.they are being held on only by an O ring.so twist and pull them out.then fallow the procidure for cleaning them.or send away to be cleaned.

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.

login and read all steps. that be best , then ask questions?

FIRST YOU NEED TO RELIEVE FUEL SYSTEM PRESSURE BY REMOVING FUEL FILLER CAP THEN DISCONNECT FUEL PUMP HARNESS OR UNPLUG FUEL PUMP CIRCUIT RELAY, THEN START ENGINE LET IT IDLE UNTIL DIE LACK OF FUEL.TO REMOVE FUEL INJECTOR YOU NEED TO REMOVE FUEL DELIVERY PIPE WITH FUEL INJECTORS AS A ASSEMBLY TO REMOVE FUEL INJECTOR.YOU NEED TO TAG NUMBER ALL VACUUM HOSES AND PCV VALVE,NUMBER TAG FUEL INJECTORS WIRE CONNECTORS SO YOU CAN PUT EVERY THING BACK IN RIGHT PLACE.

Hello
Here is what to check let me know if you need help checking this out
most common misfire causes on the cars I've worked on have been:

1. Spark plugs
2. Spark plug wires
3. Ignition coil
4. Fuel injector
5. Wiring to fuel injector
6. Timing Belt
7. Vacuum leak or stuck open EGR
8. Contaminated fuel or bad fuel pump
9. Weak compression
10. Blown head gasket

A bad fuel injector can cause spark plug issues. If the injector does not supply enough fuel, the cylinder(s) without enough fuel will run hot, often damaging the spark plugs.

But your mechanic needs to make sure that the injector is the issue and not a fuel pressure issue from regulator, filter, or pump. Hopefully he/she has already done those checks.

As far as the labor cost being less the spark plugs wouldn't be removed during the fuel injector replacement. Even if they did, most mechanics won't cut the price. But if you are a regular customer it can't hurt to ask.
