on the fuel pump i think granatelli make a high performance fuel pump but on the application it says gm cars same for eblebrock(pn 1733) get in touch with them and find out. they will be about the same price as a stock fuel pump i think.
are all 6 of your injectors bad? i have 4 94 dohc injectors laying around that i could sell u for 20 bucks. they worked great when pulled. these engines use 23 lb injectors the 3.4 pushrods use 17 i think. and i have heard the dohc injectors have a specific spray pattern not sure on that though.The Official Rotating Mass Nazi -
I think he means any 3.4 DOHC, in which case the answer is yes they will work just fine.
Secondly, an aftermarket fuel pump is a waste of money if you are under 300hp, of which I'm assuming you are considering you are using stock injectors. A bigger fuel pump will do nothing for performance.Comment

u are right it prolly won't do anything but they cost about the same as a stock replacement and he will have it there in case he decides to make some power like going turbo/supercharged. or he can get a 96 rail and jack up the fuel pressure a few pounds safely.The Official Rotating Mass NaziComment

Will the 96>97 drop right in to my car its a 91 ? I talked with some one at RC.. a injector place ,and he said because mine are leaking down . they probably have dirt in them so try some injection cleaner first he said its hard for the valves and needles to where out ..?does that sound right? My Z has 225,000 on it...Comment
