So, any ideas? Here's where I'm at.

There are a few threads discussing it. Pretty good tips in them too. Search the forum.

I definitely wouldn't be using an engine hoist though.

Already tried everything else I found in the forum. Trust me, this wasn't my first idea either.

Success! A sledge hammer helped "pop" them out!

That's scary.

I recall a forum member doing something along the lines of threading onto back of injector with a slider hammer like apparatus. Sometimes I find it easier to goggle to find things on here rather than do inside the site searches. I'll try this.

I did injector #1 on my car, all I did was remove the retaining nuts off of the retainer plate, then use an E-6 external star socket and tighten that stud up, it will force the retainer plate up and take the injector with it, I have over 100 miles and it was super easy to get the injector out

[CvilleBill]

I used a lug nut that I ground two sides of flat and a slide hammer with jaws. I was surprised at how much force was needed. I was also surprised at how dirty the hole for the injector was.

Im surprised how much rust those fuel feed line nuts get on them. What are they made from? Just generic black steel? Even here in CA where rust doesnt exist on cars my feed line nuts are rusting.

All 6 of my injectors were A seriousssss PITA. I used a bmw diesel injector puller, I found on eBay and the slap hammer.

This is how you remove them "old world style":

One of the comments from the video was pretty interesting:

"Here's the best and easiest way to remove these stuck injectors (without any special tools): You take the engine covers off, and loosen the two nuts that hold the injector in place. So you should have like 3-4mm between one nut and that metal plate that holds the injector. Do the same for the other nut. Now start the engine and let it idle. While the engine is running watch the injector and listen carefully. When you see the injector shake a bit and also hear a tapping noise, it means that the engine popped the injector out. You can also feel the injector jumping 3-4mm if you put your hand on it. You can also rev the car a bit (under 3500rpm) or take the car for a little ride (if the injector is stubborn). It is best that you stop the engine after the injector pops, because you risk ruining the thread under the bolts. Although you risk ruining the thread, it never happened to me and I have removed many injectors using this procedure. So as the engine warms up and the metal expands, it loosens the grip on the injector, and the engine's compression pops the injector out. Don't forget to grease the injector with graphite grease (which withstands high temperature, white color) when you put it back. Best of luck!"

I think my engine hoist was less sketchy than that is

[DozerDan82]

When I pulled mine non of them were 'that bad'

a big factor is getting a penetrating oil into them. dry o-rings do not like to move, esp when there is crud around them.

I soaked mine in Kroil, then they all popped out with a mini slide hammer I fashioned together.

^ nice!

I made a DIY here on how I did my fuel injectors:

I actually followed your DIY and it was very helpful. Unfortunately, my injectors were quite a bit more stuck haha!

So is it absolutely necessary to remove the intake manifold?
