i've read you can get the rail out without pulling the mani.i guess if you take the tb off and some other part's it give's you more room.i ended up pulling the intake because i was installing top feed rail and the resistor harness with the clip's for the injector's.wish i could give you a better answer,but i haven't seen any step by step direction's

Yes, I did remove my TB,the ISC and the throttle linkage and the crossover tube.
Removed the fuel line from the FPR and it was real easy to get to after that. It really helps if you have the Racheting wrench since its low profile and the six bolts are eay to get to.

Dude, he has a 1JZ. totally diff engine.

Johnny. I did mine without removing the manifold. It wasnt the easiest thing in the world, but it worked.
I removed the Throttle body bolts so I could move it around and removed the ISC if I remembered correctly too.
Unbolted the lines for the rail and just popped out the rail bolts and pulled the rail off.
The trick is once the injectors are out of the manifold is to try and rotate the rail around to fish it out.
Not easy, but can be done.

I had to replace a CPS on a 2J this last weekend.... Took about 3 Hours.

Pulled off the upper plenum/intake and was able to easily access the rail and injectors.

This is REALLY what you want to do. Then you won't have to worry that the injectors did not seat properly or that you did not pinch a grommet or O-ring.

From what I remember, it's just as easy on a 1J (if you've done it before). The 1st time I pulled a 1J harness (while in the car) it took me 7+ hours...CRAZY. I know better now...(tricky Fing bolts holding the harness plastics to the manifold... I hate them bastards).

Had I thought of just pulling the intake plenum off, I woulda been done ALOT sooner.

I know that he has a 1jz, so do I .

I know you do, but you posted instructions for a 7M.
Read what you wrote and you will see why I posted that

Where is this throttle linkage and crossover tube you mention on a 1JZ?

that still does not prove that I was talking about a 7m :
Throttle asembly/ cable = throttle linkage - thats is what I call it.
Crossover tube? Its the pipe in the rear of the valve covers and thats What I call it.... but why are we arguing about this....its not even on topic....

I installed/removed my injectors while I was doing my cams, so the valve covers were off. That made things a lot easier. But to remove the injectors themselves just unbolt the support plates, grab a towel to grip the injectors, and use el nino force to pull those bastards out.
