Dohc ZC in my 89 Crx Hf body.

Hey Guys! Here again with some more questions.

So with the car not running, I had to do some diagnostics. I had already checked for spark, compression, and fuel(at least the fuel pump). Everything was good, and it still wouldn't start.

Last night, I pulled the injectors. They are SHOT. the FPR Is bad as well. I smelled the vacuum line for fuel, and guess what? A Shit ton of fumes and some fuel came out. Everything was oem without previous replacement.

So I guess the real question is this;
Where can I find some good injectors for a decent price? I'm not really trying to get a lot of power out of it right now. Just running right. So I shouldn't need to go any higher than 240cc MAX. I found these guys on ebay. They say they're oem.

Also, should I get an oem fpr for 140 at an auto parts store, or just buy an adjustable aftermarket one for 50? I just don't know if it would be good enough to last. Or should I say FCK it and just find one at a junk yard?
I found this on ebay.

What injectors are you running now and are you using a resistor box?

FPR's don't go bad that often so finding one a the yard wouldn't hurt.
I'm running a resister box. The injectors are peak and hold. Not saturated. And I was running on stock injectors. In fact, they were the original injectors.

What's wrong with the injectors? Injectors aren't a wear item, and it would be extremely rare for you to have more than one failure, if any.

I would check each of the injectors for continuity and resistance, and if they check out, you might just need to have them serviced.

I pulled them out, and they're gummed up pretty bad. All of the rubber is falling apart. O rings and such. The filters are dark. Plus, getting them serviced would be more expensive than the set I posted from ebay. At least from what I've seen so far.

Servicing will be between $15-25/injector and you get a flow report with the results.

Buying injectors off eBay (unless they've been serviced), good luck?

All four of the ones I found were refurb. But I don't mind. Haha. I would be paying for all four to be serviced with the old ones. So a lot cheaper just to buy some

I'll point you to what he is trying to say...

Generally unless the injectors are racing customizable units or many diesels injectors cannot be rebuilt or remanufactured.
some plastic housings can be reused with brand new internals but not the metal body style you have.
They are sealed when they are built and trying to get into the pintel, disc or coil will destroy the unit.

They can be cleaned, tested, new filters, pintel caps and o rings thats it.
The problem with many ebay $100 sets is these guys buy cores by the barrel. they have no idea where the units came from or how many miles are on them.
There may be 50 of the same type in the barrel. they dig sets out, clean them up and flog them.

There is no guarantee they were cleaned properly or the flow measurement they take are accurate.
Many of these guys just static flow them and find 8 (example) that flow the same and there they go.

Auto flow which closer duplicates the actual running of the engine is much more accurate but it also has a much higher discard rate. Too much trouble for many.
Maintaining the equipment is also important in obtaining accurate readings, old fluid that may have cleaning solution in it is inaccurate.

There is a lot to know and a lot of diligence involved to do them right.

why donty you spend $10 and clean them yourself enough to verify if they really are the reason?

couple small pieces of hose, some wires, a spare injector harness plug, a resistor if necessary, and a can of carb cleaner.


barely tapping the wires onto a battery will activate the solenoid and let the cleaner flow.


plenty of videos online how to do it.

sending it in for a cleaning service is your best bet for getting them clean.



an OEM injector is far higher in quality than any ebay garbage

I Looked up a few videos on how to clean the injectors. it seems easy enough. Can I use a 9v battery? Or does it have to be a 12v source? And all of the rubber is old and cracked. I'm guessing I should buy a servicing kit with the o rings, filters, and boots(kind of boots?).

you are saying you found a few how to videos and asking me if a 9v or 12v battery is needed?


ebay has a seller that offers oem honda rubber orings for under $35. there are off brands for $15 that have been successful.

remember to lube the orings with petroleum jelly before install

I only watched like 3 videos. They were all using a car battery. thanks for the tip on the lube. I wouldn't have thought to do it.

They sell this kit at o'reilly. It doesn't come with the screens.

Is it okay to just run some cleaner through it? None of them are cracked or broken, just darker than normal.

those kits only cover a SINGLE injector.

EDIT description is very vague. I would ask in person. perhaps they do cover 4, but generally they are per injector as they can cover multiple vehiclkes this way (example, v6 and I4 cars, instead of 2 part numbers)

buy online for money saving.


lubing the oring is forgotten by many. it is a very important step to ensure proper sealing, as going in dry they can bind up slightly and cause random fuel leaks

I'm gonna have to just go there and check it out. I could have been reading on another one that said a set for all four. Thanks man

Wow i've never heard of fuel coming out of the vacuum line on an OEM FPR...

I'd just get a wrecker one. There's a lot of similar but different OEM styles though so maybe take your one with you and check the angle on the fuel fitting and the bolt spacing to the fuel rail hole.
