2009 LC 200 Fuel Injector Removal & Service

[Jah310]

Hey everybody,

My 2009 Landcruiser has roughly 200,000 miles on it. I’m looking to have the fuel Injector serviced due to what I believe to be leaky injectors, causing long difficult warm starts. I’ve recently changed out the MAF sensor all the O2 sensors both speed sensors and the PCV valve as part of preventative maintenance. Also the fuel pump was starting to fail, so that’s been replaced.

The long starts have been on and off for the last six months or so, but ever since getting the new fuel pump it seems to be more consistent. This seems to makes sense given the old fuel pump wasn’t pushing the proper pressure and now that the fuel pump is minty fresh I believe one or more of the injectors are leaking after shutdown, specially if the car has run for a while. The unmetered fuel in the combustion chamber could be creating an overly rich environment upon restart. Once the car starts, it runs flawlessly - absolutely no problems. I have no codes check engine lights or anything at the moment.

It seems like pulling the injectors should be pretty easy however I can’t seem to find any write ups or YouTube Videos specifically for the 5.7L LC 200. Knowing the tundra runs the same motor I’ve reviewed those however, the instructions I find for the tundra doesn’t seem to involve removing the intake manifold whereas anything I can find regarding the LC 200 does require removal of the intake manifold.

Can anybody lend their experience or advice on removing the injectors. I plan on sending them out to RC engineering for full rebuilds.

Any help would be much appreciated.

Thanks

Classic leaky injector hot start issue-
I've used RC in the past for matching high flow injectors in the past on big turbo and blower engines - never used their cleaning services (too far for me to ship and I have a cleaning stand). Solid shop with a good history.

Pulling the rails is easy on the 5.7. Pull the two hose fittings and then 2 bolts to pull the rail and injectors. Do the front hose fitting first so you can see how the locking collar works (lift the orange outer portion radially off the pipe then slide). Have RC send you a handfull of spare o rings for the injector/rail connection in case you tear one. they are pretty tight so do not assemble the rail with the o rings dry.

Edit- You have to pull the airbox to TB pipe and resonator but the intake can stay on

Brilliant thank you. Good to hear the positive feedback on RC. They’re fairly local to me so it seems like a no brainer. Good call on the extra O Rings.

So in your experience, no need to pull the intake prior to removing to rail?

Thanks again.

intake stay on. use a compressor and blow any crap out before disassembly but there is no reason to pull the intake - the rail is like 1.5" outboard of the runners- tons of room

Awesome - thanks. That’s what I was hoping for. Cheers

Another RC endorsement here on a few different sets of injectors over the years. Great business.

This has been on my radar for a while even though I don’t have the hot start issue.. just clearing 220k and figure it couldn’t hurt.

OP if you think about it please post with your results.

Yep will do. Not exactly sure when I’ll get around to doing this but once I do I’ll circle back
