I have been looking for some OEM 2.8L Fuel Injectors, ACDELCO P/N: 217284, with RP stamp number: 5235210, at the used parts yard.

According to RockAuto that part number was used on a number of 2.8L GM cars from '85 to '89.

I found an '86 Olds Cutlass Ciera with a 2.8L, but the injectors were different than the RP #5235210 stamped injectors.

This is what I found:

(4) Stamp #: 01D0728, or maybe 0100728, silver non-painted body

(2) Stamp #: 01D0398, or maybe 0100398, black painted body, other letters/numbers on it: AB and 105

Are these usable and work well for the Fiero 2.8L, and can they be a mixed combination like the 4 & 2 quantities above that I found on the '86 Olds Cutlass Ciera?

Thanks for the help.

If I was going to change my injectors on my V6 fiero, I'd buy new ones.

Yes, they may cost alot. For me, I think its extra security to know you'll have a trouble
free part. BTW, injectors are fragile components. You don't wanna drop them.

Make sure you replace the seals on the bottom. Those aren't expensive.

I'm sure GM still have these available for the fiero, but be prepared to pay.
If not, your best bet is to do what your doing, junk yard find. You can't expect
to get perfect part there, but them may do the job.

The bottom line today with my fieros, I replace everything mechanical and electical with new parts.
Since the fieros are over 25 years old, alot of parts are near or on there way out.

fierogt28, Thanks for the info.

The main reason I am looking for some OEM injectors is that my '87 GT 5-speed daily driver has injector issues.

There is a local company in nearby Norfolk, VA that will do a clean and test, but when I pulled the injectors from my car, there were only 2 of the OEM P/N: 217284 with the RP and 5235210 stamps. The other 4 were Ford injectors, which I do not want to re-install back into the car.

The local Chev. dealer said the GM P/N: 217284 has been discontinued since 1996, and any still available are at least $176.89 each.
I am not going to spend that kind of money if at all I can avoid it.

Pep Boys, O'Reilly and Advanced have some remanufactured injectors, by BorgWarner, they can order that are affordable and have a core charge.
If I knew they were rebuilt RP Rochester or AC-Delco units I would give them a try.

I have a few good 2.8L spare motors I can pull some more injectors off of I have to, but I'm trying to hold off on doing that until I see I don't have any other options.

#5235210 shows up as an 88 Firebird injector.....and rebuilds are available on the internet for $40 ~ $80. I don't know why they do not list the Fiero too, but I would think it's the same thing.

Ok, I see what you mean.

I'm suprised that Ford injectors did the job until now.

Years ago (in 2005) I have a batch of used GM injectors that I gave to a fellow
fiero friend. If I would of still have them, I would of offered you them at no charge.

The reason why, is I had no past history on them and you could of had them bench
tested and cleaned. I think that would of been a better cost alternative.

I am hoping the Ford injectors that I found on the car are the issue. They don't look new, so they must have been in there a while.
The car has never really run the best ever since I bought it, towed it home and finally got it running a little while back.

Gall757, do you have a link for those '88 Firebird rebuilt injectors?

Thanks for the help.

When I bought injectors for my 2.8 V6 from the parts store, some of them were silver (no paint), and some were painted black on the center section. I remember the parts counter guy saying they were two different part numbers, but were interchangeable. I don't remember the part numbers, though. But they're still in my parts bin, in a zip-lock bag. If you want, I'll dig 'em out and see if there are any part numbers stamped on them. Or you can have them, if you'd like. I won't be using them anymore.

Blacktree, Thanks for that great offer!

So far, with help from friends here in the local VAFA club, it looks like I will be able to bring enough used OEM injectors over to the local shop in nearby Norfolk for a clean and test, to hopefully have a full set of 6 that pass the spec test and I will be able to install them next weekend.

Thanks again for all the help!

I don't know if the website listed above is for the Fuel Injector Connection, but if not, they are an excellent resource for replacement / remanufactured fuel injectors.
There is also someone on PFF who tests and rebuilds injectors for a very reasonable amount, so you might want to look him up through the archives.

I was also going to suggest Fuel Injector Connection. They have a Blue Demon series that they will tune to your requirements. You should get pintle injectors for stock ECM applications. John knows what you need since he used to race Fieros. Price for 6 should be under $150.

Actually, I happen to have an old set of OEM Fiero V6 injectors. I forgot I had them. The part number stamped on the side is 5235210. Hope that helps.

Your `87 GT is not the only one which has had "injector issues"; in fact, the following thread seems nearly tailor-made for you because of a comment within it about a stock `87 GT 2.8L that almost sounds like you wrote it:

Source of above quote: "FUEL INJECTORS" thread of 2012 which can be accessed via Pennock's Fiero Forum link, https://www.fiero.nl/forum/Forum2/HTML/126508.html

I'll repeat below the basics of what I said in that thread to its originator only about new injectors (since comments about "reconditioned" injectors already seem to be well-covered here):

Two good sources for those brand-new injectors are Summit Racing ( http://www.summitracing.com ), and Jeg's High Performance Parts ( http://www.jegs.com ), each of which are large, U.S.-based, discount-oriented, mail-order houses with whom I've had several successful business dealings in the past.

Compared to OEM injectors, the price for a set of six 15-pound Accel injectors may seem "too good to be true", but that is only because GM's injector prices for the V-6 Fiero have been so high....

Were I belatedly to add one thing to that 2012 thread now, I might have said GM injector prices for the V-6 Fiero have not merely been high --- but RIDICULOUSLY high.

However, it sounds like you already discovered that outrage on your own, hdryder:

I don't blame you, and I hope this thread helps you avoid exactly lthat --- whatever you end up doing.

If you can't get originals then I'd probably get a refurbished, flow matched set from some reputable injector shop. Or if you buy new ones, get a matched set of 6. I don't recommend mixing different part numbers - the ECM has no way to compensate for differences between injectors on the same engine. There can be subtle differences in how they behave, even if they have the same overall flow rating.
Whatever you get, make a point to write down the part number you receive. You might want that info later.

Thing is, I'm not sure that even new injectors will be truly designed to match the originals. I fear there's a lot of "best fit" substitutions that get made by pretty much everybody. Many of these newer injectors probably really are better than the originals, but if the ECM isn't programmed for them then it could cause a headache.

I bought a matched set of 6 refurbs from Precision Auto Injectors a couple years ago. They work fine, however, the injectors they sent were not truly the correct ones for the Fiero. They did declare this openly, and they included a note saying the ECM would adjust, but when you study the details it turns out this isn't completely true. The problem is subtle, but it's exaggerated by a slow ECM like the Fiero uses. The factory ECM tune had a surging idle problem with them. The correlation wasn't immediately obvious because my old injectors were also not originals, and they had the same problem.
I believe the part number of the injectors they sent correspond to a 93-95 FBody 3.4L. I got them working but it required making chips.
At the time I ordered, they didn't actually have a listing for the Fiero. They do now, but it says "OEM Multec" on that page so I think they're still a substitution. Other injector shops might have the original style, I don't know.

If you want to minimize the chance of any ECM tuning issues, then the best route might be to get hold of some true originals from junkyards, other Fiero owners/etc and have the whole matching set professionally cleaned and tested.

Hello,
I have a set of refurbished Fiero 2.8 injectors that I bought a couple of years ago intending to install them. Couple months later I was tipped off to a dealership that was closing and found they had 7 new original sealed injectors that are identical to mine so I bought and installed them.

If anyone is interested in the set of 6 refurbished injectors that I have I'll sell them cheap, $70. plus priority mailing to you.They are in sealed zip bags and stored inside (in my closet) so they have not been exposed to weather. PM me if you are interested.

PS.... forgot to mention. These are the flat bottom type injectors, NOT the pintal type. They have new seals on them also.

As fierofool posted above, our ECMs were designed to run pintle-type injectors.
People who install disk or multec type injectors frequently report a hunting idle problem.

That being said... Most any injector of the pintle-type, that meets the flow characteristics of our stock injectors (15 lbs at the specified fuel pressure) should run just fine in our engines.

BTW... For people who build up hotrod 3.4s, 19 lb Ford Mustang injectors are the preferred piece. (For more stock setups, 17 lbs will do.)
The ones I sourced for my 3.4 were Bosch pieces, designed as a drop in replacement for a 4.0 Jeep.
Just because an injector is used in another brand of vehicle doesn't mean that it won't be happy in yours (or ours) as long as the characteristics are suitable.

Is the price for these so low that they are junk?
