Fuel injectors are computer controlled spray nozzles that deliver fuel to your engine in precisely controlled volumes. They are one of the keys to modern efficient and clean engines. If a fuel injector is dirty or failing, it can present symptoms such as rough idle, engine surges, rich or lean conditions, and check engine lights. Replacing a problematic fuel injector with an engineered to fit TRQ replacement part right away is essential to the health of your vehicle’s engine. This video shows you how on your 2000-2006 Chevy Tahoe.

Your videos are great and we can actually see what you're doing. I think I'm a mechanic now.

Thanks for the video! Did the repair today and didn't have any issues

[jimbradley]

Very well done I watched another video in similar detail a little bit longer. But this gave me more confidence to install those injectors completed on the fuel rails.😊

Straight Forward, Works on the 1999-2007 Silverado, Suburban, Tahoe, or any SUV with the 4.8/5.3/6.0 LS

Don’t forget to bleed the air from the line. You can see the black screw on cap here behind the green screw cap halfway back on the side. All you have to do is keep the top black cover off and look for the small black cap on the aluminum tube going across the top of engine. With the engine is running take the black cap off, place a container underneath the bleed valve and press it, not to hard though it will spray you with gas. There is no way for the air to get out of the system being it is closed. If you do not do this your vehicle will have a rough idle and a long start. Release pressure until idle is back to normal if you do not do this the vehicle will run like garbage and gas mileage will be the same as before you installed new injectors. You can see what I am talking about at 0.29 seconds into video.

Not too bad of a job, but how many times have you cursed about a engineer? 😂 Great video by the way!

[cooperwoods]

Stupid question, if I just need to replace one injector (cylinder #2) do I need to actually take everything apart or is there a way to just replace it without doing the first few steps?

[Treestormer]

Where do you get the “key” that removes the PCV hose? Also is that necessary to take it off?

What are the correct fuel injector or part numbers for a 2005 chevy tahoe z71 5.3....4x4...Vin...T..

[mauriciollamasromero]

Where can I buy that quick disconnect tool for the fuel hose thank you

[billcoley]

Omg you just uploaded this. One question I have for you if you do not mind. I just removed my fuel rails and cleaned everyone of my injectors and I put them back into the fuel rail before I went any further. When I put the completed fuel rail back on the motor which is a 2007 5.3. They don’t look like they are far enough down but I don’t see the o ring. The bolts that hold the rail down did not need any pushing to start the bolts completely down finger tight. Does this sound normal? Thanks in advance

Aren't the fuel injectors coded to match individual cylinders? Looking at mine and I see alphas and no numbers designations.

[Jaguarspaw]

I have 45 psi and it seems it seems like it starts but dies right away. I have spark and injector pulse. Replaced the fuel but still no start. Is it fuel pressure its supposwd to be at least at 48psi for flex fuel. Could it be that? Injectors tested around 12.7 to 13.7 ohms.

[jamessmith]

Where do I get the special tool to unhook the fuel line?

[Rick-qfde]

Wow, with hands like that you should have been a gynecologist... 😮

This is a mess of an instructional video. Sheesh.
