What injectors do I have?

[84convertablegt]

I'm looking for a part number / Lb./hr. rating. There is alot of conflicting info out there. Lets start with what I have: 2000 Ford Ranger Vin "V" Flex Fuel 3.0v6.
OK, some sources say they are 25.? lb/hr flow injectors. 50motorsport says the flex fuel has 19lb injectors for my year. I'm confused. I think mine are going bad finally after 235,000 miles and I want to replace them with new ones, but I want to make sure I buy the right ones. The Motorcraft website lists 2 part numbers, I have no idea what the difference is. Does anyone know the actual flow rating or a part number for a Flex fuel 2000 ranger? My stock injectors are all gray, no color that I can see. They are hard to see though without taking off the upper intake, so I can't get a part number. Any help is appreciated.

I tried to answer you but I have Firewall issues on RPS (@ work).

Fredness, http://rogueperformance.com/BlueprintedFuel.html says they are 25.3.

Personally, I'd stop by an AP store, have them do the "drill down" on their computer and see what they hand you when you specify FFV 3.0.

I don't trust auto parts stores. Advance thinks my ranger has a distributor!

well technically, it does have a distributor. its just topped by a sensor rather than a cap and rotor.

flex fuel 3.0's have 25lb injectors. the reason the only color you see is gray is because the color designation is on the injectors "hat" which is currently stuffed into your intake manifold. you cant see it without pulling the injector out.

pretty good price;

The only problem I have with folks selling cleaned up injectors with new screens is that the coil inside has varnish insulation. Many of these folks test them and thats fine, but the coils can short from gas eating the varnish or open from the vibration of the injector operating, and used ones already have the miles on them. Unless I was hurting BAD for money I'd buy new.

Just to clear up mis-information. 99-2000 rangers have 21 lb. injectors. They are kinda special Denso parts. 221cc's which equates to about 21 lb./hr. i replaced mine with the newer style Bosch orange injectors, commonly used in mustangs, etc. They state 19 lb/hr but flow 210 cc's which actually is over 20 lb/hr. They are only 10 cc's different than the stockers and cost and perform 100X better. I know some of the older flex fuel cars used 25lb injectors, but this is not the case on 99-2000 3.0 rangers, they used 21 lb/hr. injectors which can be replaced by any standard 5.0 Mustang 19 lb. injector.

I have the same truck with no where near as many miles a syoubut like to gather info. So, I did a search at motorcraft.com and came up with a part number CM4889. Cross-referenced at rockauto and came across the second injector CM4935 but only found it at rockauto. I'd definitley go with the CM4889. First one I found and it is made by motorcraft.

Yeahp. Motorcraft CM4889 21Lbs/Hr. if I recall correctly 99-2000 Part no.

Yes, I know this is an old thread, put people are still reading it...

Anyways, either of these Motorcraft injectors will work, just don't mix them.

Regardless of what certain websites say, this is what they flow new...

Motorcraft CM4889 (XL5E-9F593-A2A, XL5Z9F593AA)
14.0 OHM, 222 cc/min, 21lbs/hr

Motorcraft CM4935 (XL5E-9F593-B2A, XL5Z9F593BA)
14.2 OHM, 222 cc/min, 21lbs/hr

However, the CM4935 is only listed for the 2000 Ranger "vin V". While the CM4889 is listed for the 1999-2000 Ranger "vin V" or the 1998-2001 Mazda B3000. Not sure why that is, but I own a 2000 Ranger so it doesn't really matter to me.

All I know is, it's not good to mix injectors with different impedance ratings. So since the CM4889 are 14.0 ohms, and the CM4935 are 14.2 ohms, I would avoid mixing them. Just choose one or the other.

Oh, also, if you never run your truck on E85, then as mentioned earlier in this thread, it might actually help to switch to the Mustang 19lbs/hr injectors. The injectors in the FLEX-Fuel Ranger are over-sized for E85 usage. If you don't use E85, you don't really need them over-sized for stock performance. Personally, I just left them in, because my truck is not exactly stock anymore...

why do you need injectors ?

I had a dissapointing P.O.S. 89 toyota 3.0 4x4 that started leaking gas out of the top of 4 injectors onto the outside of the engine at 105,000 miles.
The stock ones were about $200 each so I got used ones from a wreck
.......at least when the timing belt broke it didn't bend the valves

I guess it depends on how many times you feel like tearing it down... Personally I don't want to do it again for awhile... I just replaced mine after 220,000 miles on the originals, and I hope to get another 220,000 out of the new ones.

Also, I think it also comes down to performance too. If you just want it to go down the road, then who cares really. But if you want it to perform a bit better, then replacing them with new ones is the way to go after a 100,000+ miles.

In everything there are levels to how much you want to get and spend.

For injectors those choices are,

1. Leave them in there 'till each one dies one by one and replace them as necessary.
- - - Great for the Do-it-yourselfer that has lots of spare time....

2. Replace them all with junk yard specials.
- - - An hour or two of your time and $10 and you have semi-used injectors. Good choice for the daily driver on a budget.

3. Replace them all with re-man's
- - - Will cost you around $140-$200, but they are nearly as good as new ones. If you can't shell out the extra $100-$150 for new ones, this might be a better choice.

4. Replace them all with new injectors.
- - - Will cost you around $350 for a full set, but they are brand new. I got a set wholesale for $210, so do your homework first.

5. Replace them all with flow-matched injectors.
- - - If you are looking for top performance, then you need flow-matched injectors. These also come in Re-man's and New, and depending on how closely they are matched, they may be quite costly....

It all just depends on what you are looking for and what you are willing to spend...

FYI, I just bought a brand new set of the Motorcraft CM4935's above for $210 (that's all six injectors!). So that wasn't too bad.
