I have a '93 4Runner with 3.0L v6. Does anyone have instructions, or know where I can find info on changing out the fuel injectors?
Thanks

I had to do mine twice. First, remove everything attached to the intake manifold: the 3 cables, bunch of hoses. Make sure you draw or take pictures where all the small hoses go to (use masking tape to ID them) and the position of the cables. Remove the large air intake hose.
Disconnect the small fuel line on the left side. Disconnect all other fittings and wires that you can see that will interfere with the removal of the manifold. Just disconnect what is necessary. Do not disconnect the lines under the manifold.
Then remove the manifold bolts/nuts, 4 long bolts, 2 short bolts, and 2 nuts.
Lift up the whole manifold, there are 2 rubber hoses left-rear underneath that maybe hard to remove.
Once that's done, loosen the fuel rack lines and unbolt it. The injectors can now be inspected/replaced. Do one side at a time.
You'll see how it will go it's not that bad. It just seems like a big undertaking. Make sure the o-rings are good before you put the old injectors back in or you will have fuel leaks. Good luck.
