GM has a special puller to pull the rail out with the injectors but after talking to the techs at the dealership it does not work most of the time. If you reuse an injector which I would never recommend, you need to replace the Teflon seals. There are special tools to slide them on and then resize them. New injectors have the seals already installed. Thanks for the comment.
Not sure about GM but VW/ Audi injectors typically remain in the cylinder after removing the rail, and if the injector is stuck then there is a small slide hammer tool that can be used to remove then injectors
So I need to depressurize the fuel system? How can you do that without a scanner/device like yours? can I pull a fuse or disconnect a wire to the fuel pump?
If you have a leaking injector it will have lost pressure by the time you get the intake off. Either way put a rag around the fitting on the high pressure pump and Crack it loose. Safety glasses and no open flames. There's not a lot of volume possibly couple table spoons.
Much better way, there is a fuse for the high pressure fuel pump, start the eng and leave running, pull the fuse, let the eng die on it's own, takes about 2 min. No more pressure in fuel rails. NOTE: those fuel rails have enough pressure in them that a small pressure stream of fuel CAN and WILL CUT YOU! Do not open a high pressure fuel line without de-pressurizing first! They use high pressure liquid to cut and shape steel.......your finger is nothing to it! And yes people have had finger cut completely OFF!
Whatever happened to the oxygen sensors being affected by the silicone in the dielectric grease? Technicians love the clear grease for assembling things that have orings, but I tend to use other lubricants or dry fit like the specs call for on the fuel injection system.
I doubt that dielectric grease would affect the o2 sensors since it's not curing like silicone sealant where fumes can collect in the crankcase and be drawn into the intake by the pcv system. I'm not an engineer so I may not be correct...
I got a lv3 engine, i did a injector job and the white seal was not from factory, i installed everything on the kit and now is throwing a p0300 code, is possible that the v8 use it and v6 no or they’re the same.
If you're referring to the upper white seal on the injector that was added in around 2016 to help seal the body of the injector to the cylinder head. It helps in future removal. I'm sure that's not you're problem. P0300 is random misfire but it likely is not random. Check live misfire data and misfire history to see what cylinder is actually the problem.
Great video bro! I got a question I have 6.2L cadillac escalade 2016 with 110000 miles on it has code P0302 cylinder #2 already replacement spark plug amd wires and new ignition coil! Won't change anything still has misfire, could be the injector #2?
It could be the injector but could also be a collapsed lifter or bent pushrod. Cylinder 2 is not one of the AFM cylinders. Does it have a tick in the engine at an idle? Do a relative compression test. Maybe pull the right valve cover off and check valve movement. Are you certain it's cylinder 2 that is missing. Can you feel it shake. Does it count active misfire on cylinder 2.
@@PhillipBailey yeah does has misfire! I'll will try doing relearn, band also I'll try to replace the injector see what does, do I have to replace all 8 them o try just #2 or 2,4,6and 8? What do you recommend?
Yes they are a bitch to get out for sure. Took me several hours to get them out. The dealer has a tool but I'm told it doesn't work either. I found if you force the clip off and leave the injector in the head then remove the rail so it's out of the way then you can grab the injector with vise grips and twist it back and forth. If it breaks off your probably going to have to remove the head. Good luck.
I have a silverado 2017 V6 4.3, and it’s throwing a p0306 code and a p219b, you think it my be my injector, I clear the code and sometimes it takes 3 weeks to reappear back or some times less time.
Good luck with this... is there a noticeable misfire? Try plugs switching the coil, flush injectors, swap O2 sensor side to side, make sure there are no exhaust manifold leaks, proper air filter, no intake leaks, clean tge intake valves. Clear the codes and sell the truck...
@PhillipBailey it's not consistent and tells us it's number 5 acting up sounds like pinging took off the valve cover and all of the valvetrain is moving properly with nothing loose and I'm getting consistent 180psi out of compression test. Over 200000 miles and there is so much carbon on the intake and valves ....heard these are known for having carbon build up causing a misfire or pinging witch I hear randomly and doesn't sound loke a valve....just getting some conversation with you pretty sure the injector is leaking or the pump is leaking so mu h fuel in the oil
@PhillipBailey yeah thays what I'm thinking the carbon can actually stay red hot causing a pre ignition....when I removed the driver side valve cover to look at the valves every thing was disconnected the noise wasn't happening but if we switch Coils and plugs it stays at 5 does not travel it also reminds me of the common rail cummins when the injector starts going bad it has a funny clicking
I have a 2017 escalade with 6.2 engine. Auto zone code scanner detects code p219B as a secondary code while the snap on scanner doesn’t detect anything. Check engine light is not on. I just put new injectors recently. Any help?
That's a fuel imbalance code I believe. There are a lot of things that can cause that. Are the O2 sensors original. Aftermarket ones are often problematic. Try swapping the two forward sensors? Exhaust stock? Exhaust leaks? Plugs new? Air filter new and OEM?
@@PhillipBailey so initially injector number 6 went bad so I ordered a brand new set since the car has 140k miles. It turns out dealer provided wrong injectors. After couple days I get the right injectors, I put them on and car drives fine. Also, I use liqui Molly injector cleaner in the fuel tank. Could it be that autozone is pulling an old code since I don’t have a check engine light. Usually P219B shows with a check engine light. Air filter is not oem but oxygen sensor are oem never changed. Truck has 140k miles
@rideshareg7608 AutoZone is likely scanning with an OBD2 scanner which may be retrieving a pending code. Did you clean the intake valves when the manifold was off?
@@PhillipBailey no never cleaned intake valves, only used stp pro valve kit cleaning which is done by running tube through throttle body. Never cleaned each valve by itself
The P0430 code is an indication of Catalyst inefficiency which is likely a result of random misfires and injector problems. You will likely need to replace injectors, clean intake carbon deposits and the likely change to Catalyst. It's been my experience that the 430 code is the result of the injector and misfires and once the converter is poisoned it will need replacement.
Trouble with removing and cleaning is they don't come out without destroying them 95% of the time. I have flushed then in the truck on one occasion but it didn't help.
Yes it did but be warned after fixing that you will enable Catalyst monitoring and you will probably have a cat code P0430 or P0420 after a couple drive cycles. I'm working on one now, a 14 with a P219A and P0300. Ran injector flush and top engine cleaner and appears to have cleared up the misfires but now P0430 sets...Good luck
@@joek3779 problem is the misfire will potentially damage the cat and you won't know until you fix the miss if the cats will live. When the computer detects a misfire it disables cat monitoring. As I said I have a 14 right now...
What is consider to many misfires cylinder 3 has 8 misfires cylinder 7 has 4 but no codes and I am also now getting more of a shake around 65 75 it’s more of a pulsing shake but different from the normal Chevy shake these trucks have
@@joek3779 that depends if you are talking current misfires or over the last ten drive cycles. The odd one now and then is inevitable but consistent on the same cylinder or cylinders is a red flag.
What happened to the white gaskets at the bottomed of the injectors flange? they are showed been greased, next take the injectors teflon and o-rings are greased but the white gaskets below the injectors flange are missing! Where they go? Do you install them separately? I’m confused. Can somebody tell me?
The white seals you mentioned are an update and are to be added if not originally installed. The right fuel rail had been off before so two of the injectors had them installed. The left side was original so didn't have the orings. They help keep the injector from corroding into the head and were added in production in 2017 I believe. HTH
This exact problem is why I refuse to buy any of GM’s direct injection garbage. They screwed the pooch with poppets on vortec motors and now again with this crap.
P217E indicates a problem with number 8 fuel injector. Here is some information: Conditions for Setting the DTC P2147, P2150, P2153, P2156, P216B, P216E, P217B, or P217E The engine control module detects the fuel injector high voltage supply circuit is shorted to ground for greater than 2 s.

If you clear it and it come back I would suspect a problem with number 8 injector or the wiring to it. Looks like the intake manifold has to come off. Has it been worked on before?

Got a question, what Tool did you use to get the clip off the injectors from the Fuel rail?
Just a large standard screw driver

How long does it take overall for this job? My mechanic said 2days.. i doubt it
Well it can be very labor intensive especially if the injectors won't come out easy. I'd quote 6 to 8 hrs but no guarantee that is enough.
@@PhillipBailey where are you located?
@eddievallejo8535 just outside Thunder Bay in Ontario Canada eh
so which injectors you end up changing, the ones whit high balance or low balance tanks good diag.
All of them he said.
Did this fix the p219b I have same code but it’s p219a
Did it fix??
What side did you have to change?
Do you have to reset fuel trims after new injectors installed
Yes you should.
Nope.
How did you finally removed the engine plastic cover?
The plastic cover over top of the intake must be removed and installed with the intake manifold assembly. There are access holes through the cover.

Are these injectors known for leaking and causing a ticking randomly like its pinging
If the ticking is accompanied with a misfire it's likely a sticking collapsed lifter. A leaking injector won't cause a noise.
@PhillipBailey it's not consistent and tells us it's number 5 acting up sounds like pinging took off the valve cover and all of the valvetrain is moving properly with nothing loose and I'm getting consistent 180psi out of compression test.
