injectors....again

[willmoodom]

Okay,so everyone has spike on injectors Farm swapping to testing ohms. But I haven't come across anything relating to visual inspection and whether what you see is good or bad. This is my situation... I have 2 1996 rails with injectors. One scored at pick and pull the other from some one on the board that was less than honest about what he had. Look as if he swapped some out before sending me leftovers. Anyway, at the bottom of the injectors is this plastic piece with 4 arms, appearing to be caps and holding the pointless on. After removing one it turns out that there not holding anything on. What are they for? And are there no replacements if they are needed? Although they may be broke, is the injector still good? Ill try to post a pic of what I mean or am talking about.

Pictures would help.

Who sold the rail to you?

I had some terrible luck getting a complete set of 94-96 rails.. The first set, I bought from some online salvage named Basic Car Parts. That was a rip. The right side rail had been bent on removal.. I picked up another set a Pull a Part in Memphis. The right side had a dent in the rail. It looked like someone dented it during removal or dropped something on it after they removed the plenum. Recently I pulled a set from a 94 at Pick-n-Pull that appear to be in good shape.. Once a rail has been bent during removal, I don't see how it can be straightened..

Those are the pintle caps and they regulate the spray pattern. Available online. Old ones become brittle and break easily.

heres the pic of what i got from this board member:

rail on the bottom i got from a pick and pull. guy claimed 68k on engine and with the condition of the rails compared to my p-n-p rail, no reason to doubt. you can see some of the caps more discolored then others. Anyway my question was answered thanks maxnix. Also, look at this pic. one of the injecctor tops :-) has a metal piece in it. i assume they all should have it. though one of mine is missing:

right now new is not an option at 150 or more a piece. what do you guys recommend? have current sets rebuilt or purchase remans? On some sites, when i look up injectors for a 94-96, im seeing 2 part numbers with different prices. whats the difference other than the plug? some plugs are oval some are square. but what are the injector difference? why the black mark,white mark or no mark?

Cool guy, and he has the Viton O rings also. He actually tests his fuel rails after he rebuilds them, unlike some advertisers on this site.

Thanks a bunch maxnix!! whether you know it or not, you saved me 600 bucks or more. I wasnt to trusting of sending my injects out and hoping for the best. This guy Bill is the only person I come across who details what they do, how they do it and gives good prices on everything. sweet!! going out tomorrow. all 16 injectors.

That metal part you mentioned is just an insulator or spacer that keeps the injector aligned in the rail cap. They are available separately from the dealer.

I wasn't aware of the amount, but Bill is a real straight shooter. Let us know how it turns out.

U know if the 90-93 injectors r the same?

[willmoodom]

U know if the 90-93 injectors r the same?

No. 90-93 are different than 94--96.

[maxnix]

U know if the 90-93 injectors r the same?

Early are single pintle and really do not like ethanol.

Later are rotary pintle and tolerate ethanol somewhat, for a while.
