Fuel injector so how do i do whatever i need to do with fuel injectors can the fuel injector be changed or do you clean it and if so with what

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

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

it sounds like your fuel injectors may be clogged or dirty, you can take your vehicle to a shop and ask them to clean the injectors or you can attempt to clean the fuel injector you will need a fuel injector cleaner, in order to find the dirty fuel injector you will need a fuel pressure gauge,and a fuel injector tester,both items are very cheap and can be purchased at this website www.discountbargainprices.com,

Andre, changing fuel injectors that are not faulty,damaged,leaking,etc. may not improve any performance. have checked and diagnosed by a good technician.

run fault codes to check for problems associated with the injector electrics. Check for cam/ crank position sensor as they can stop injector operation. If you have used some sort of fuel / injector cleaner then that may have blocked up the injectors with gunk needing the injector tips to be cleaned out.

Could be one or all of those things, obviously first step is to listen for your elec. fuel pump to engage and prime your fuel system, you may have a relay that's going bad to fuel pump and may wish to check/replace that before proceeding. It wouldn't hurt to change your fuel filter if it's not been changed in a while and even more so of a reason since you're experiencing problems somewhere in fuel delivery. Next you should check your fuel pressure at the fuel rail. That will show you if fuel flow is restricted or that you have a faulty fuel pump. If that checks out ok I would suggest having injectors inspected/cleaned/replaced if needed. It's easy enough to do yourself and here's instruction if you choose to do so. First step is your safety wear safety glasses and have a fire extinguisher nearby before you start, from there will need to remove each injector and have something to catch fuel in, next start vehicle and observe spray it should be an even stream (use a spray can of carb cleaner to clean injector) clean it and reinstall and repeat steps for each injector (replace faulty injectors as needed). hope this gives you a better idea to fix it, good luck and let me know if you need any further assistance

Disconnect the wiring plugs from the injectors, Then remove the fuel rail (which is attached to injectors). Then remove injectors from the fuel rail. Don`t forget to change the "O-rings", (little rubber things on the end of each injectors). Otherwise there`s a possibility of fuel leak.
Also I suggest trying to clean the faulty injector at first, It might be ok, just dirty inside.
How to clean: Use injector cleaning fluid on the end of the head of the injector. Attach minus and plus to the contacts of the injector to battery of the car or any other energy source, and start pulling the negative wire on the battery on and off. You should hear clicking sound in the injector. Use the fluid and this "technique" for couple minutes or more, until the injector starts spitting the cleaning fluid evenly, not rarely. If still the injector doesn`t spit the fluid, you might need to change it.


Hope this helps, sorry for my english. I`m a lithuanian

How could the pump failure contaminate the injectors when the fuel filter will catch all debris. Sounds like someone is trying to take you for a ride! Shop around for a honest repair shop,there out there! Have the fuel pump and fuel filter changed and you should be fine.I hate when shops try taking advantage of customers.
Good Luck hope things work out.

DO A LITTLE TUNE UP.CHANGE SPARK PLUGS.CHANGE FUEL FILTER.CLEAN FUEL INJECTORS.FILL FUEL TANK UP.AND ADD A BOTTLE OF FUEL INJECTOR CLEANER IN FUEL TANK.WHEN YOU DRIVE CAR AROUND.THE INJECTOR CLEANER WILL CLEAN OUT FUEL INJECTORS.IF CAR STILL RUN ROUGH IN DRIVE.YOU COULD HAVE INTAKE LEAK.

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.

Very detailed and car specific. There are at least three ways to do it. One is to take the injectors out of the truck and use a fuel injector solvent to clean them. Another way is to use a fuel additive to clean your injectors pour in your tank and off you go (do it at every oil change) Another way is to hook your car up to a fuel injection cleaning machine. It essentially by passes your gas tank and connects directly to your injectors to clean them with your engine running.
