Alright, I searched and checked out the forum and followed the instructions for a sohc KA.Directions don't work.I have a 93 Dohc KA.My problems is this.I disconnect everything, however, when I grab the fuel rail, only 1 and 2 injector want to come out, 3 comes out a little.HOWEVER it seems that the fuel pressure regulator is stuck, and not letting me pull the entire rail.Can someone with experience with this tell me what screw I have to take out to take the entire rail out?It's really bothering me

1,2,3 injector referring to the injectors closest to the fan, the last injector won't budge, and I disconnected the bracket, that connects to the fpr that is on the intake manifold.

If I'm not mistaken, doesn't the fuel rail just pop onto rubber donuts on the intake manifold? There's gotta be another bolt or something holding it in place or try pulling straight out.

To change the injectors on a DOHC you dont need to pull the rail. you undo the cap screws over the injector and use preffereble curved needle nose pliers to grab the injector by the 2 slots on either side at the top of the injector. gently rotate the injector in its bore with the pliers with a SLIGHT upward force while prying at the base of the injector with a megium lenght screw driver. it should then just pop out. When going back in lube the upper oring well, place the cap onver the injector and use the back of n socket extinsion to push down on it to pop it in.
