Quick question!

I have a 2000 Ranger with a 2006 engine, been having issues with the fuel pump, replaced the pump/strainer and fuel filter wtih 2000 parts, no luck, at all. We took it to a mechanic and they told us it needs a 2006 pump.

So for those of you familiar with these parts... can the 2006 fuel pump assembly be integrated with the 2000 fuel lines & electrical wiring?

Thanks!

 

Well, I'd consider checking the details on my own. What are the operating pressures required for each? I understand that FoMoCo went to a 'returnless' fuel system that had higher operating pressure at some point in time. Maybe you crossed that time line...
That said, an injector doesn't know beans about pressure, and will flow what it will flow. If you were able to put the 2000 injectors into the 2006 ports and fuel rail, they should work just fine with the same vintage pump and regulator.
Check the pressure specifications for each engine, and if they differ, try swapping the old injectors into the new engine. You should not need to change the pump & sender.

Thanks,
I'm really not mechanically inclined at all, so that answer helps me a ton! I would've never thought about looking into if the injectors are interchangeable, that gives me a lot to go off of, and really helps. Thanks tom!

p.s. any other input still will be greatly appreciated!!

 

you need to create a signature with the details of your truck. did not even tell us what engine you have. was the truck running fine for a while with the 2006 engine?

98 is when they increased the pressure and went to a return less system....

 

Well, i've been using vBulletin for years, but for the life of me cannot find the place to edit the signature, regardless here ya go (and my apologies for not posting earlier! I'm rather rushed trying to dig up this information as I have a buyer interested in this vehicle--so I do appologize for not taking the time when I first posted to include that info):
4.0L v6 supercab ranger, 126" wheelbase, 4x4, automatic tranny.

The '06 engine was installed in April of 2008, it ran OK for a year, then started idling rough, we replaced spark plugs & wires and that seemed to help, but and still has pretty much been doing that since 2009, with this past 6mo it really started going downhill, it's been "kicking" at speeds above 65mph.

Also, been having issues with the Check Engine light. Was throwing codes P0171 and P0174 along with the P0153 (I think--O2 sensor code), replaced Mass Airflow Sensor and that got rid of the first two, but the O2 sensor code was still there, hubby got the bright idea of replacing the fuel pump (as we've already replaced all the O2 sensors), did so and the O2 sensor code went away (yay!) but the 171 and 174 fuel lean codes came back.... it ran GREAT after we replaced the pump with a new 2000 pump for 48 hours, then became worse than before, not wanting to start right away. I wonder if maybe we should've replaced the entire fuel pump assembly, vs. just the pump and strainer.

 

go to user CP(it is located in the middle of the page all the way to the left->edit signature->this site might make you have a certain # of posts maybe 25. I am not sure but you can try.

p0153 is usually a bad o2 sensor, bank 2 sensor 1.......it might be worth a shot to swap that out!

*(NEVER MIND i SEE THAT YOU REPLACED ALL THE O2 SENSORS)

you need to do a fuel pressure test, koeo, koer, etc.......maybe it is the regulator?

did you check that the new pump was the same pump that came out of the tank?

 

I have been seeing a lot of bad pumps straight out of the box new. And this Ethanol fuel is extremely hard on them.

 

Hi Emily, to answer your question about a signature, you need "25" quality posts before the option appears in your usercp.

Other useful info can be found here,,, https://www.ford-trucks.com/forums/7...w-members.html

 

I could never think of a logical reason why they want to keep people from creating a "detailed signature" about their truck........it helps everyone.

 

You would be surprised how many one post wonders show up, ask a question and then never return. The magical number 25 also controls other things you can do in the community.

 

I understand about the one post wonders..........I have about 50,000 posts on auto forums.........out of those 50,000 posts I have received 2 infractions, both from this site because I tried to get someone to create a signature.......I did not know about the 25 posts........I go into an argument with the guy........the guy email a moderator and sucked up to him......they were both military "Veterans".........you could probably guess how I handled it........think "time and money"

....You are penalizing people that want to do the right thing because some do the wrong thing.........Here is the solution.......make new members complete a detailed profile of their truck before they join.........if they don't complete it then don't let them join.......that way you keep out the trolls........ I think the reason they don't do this is they actually want as many members on the forums, even if they are useless non contributing trolls.........the site "looks" better with a higher number of members

 

The mechanic did fuel pressure (but I have NO idea if it was koeo or koer...), if I'm remembering correctly, they said up until about 2/3 throttle it was ok, but then dropped off significantly at full throttle.

Yep, we did double check to make sure the pumps were the same. At first we thought maybe we just hadn't screwed down that white O-ring cap well enough, double checked it, but no luck. I wonder too if it's not the regulator cuz I double checked with my husband and he said he never specifically told the mechanic we had only replaced the pump, not the entire assembly. Hmm

And in regards to the 25 posts, not a problem! I've been on other boards that are like that

 

that fuel pressure sounds like your problem?.........you need to get full and accurate fuel pressure tests!

 

Ok, so here is what I've found thanks to the wonders of google...

Until 2000 in the Ranger is was an OHV engine, which I'm assuming has a fuel return line to the fuel pump. It requires a fuel pressure PSI of 39-40, with a 30psi idle.
After 2001 the Ranger carried a SOHC engine, which then has the PSI of 64-75. No fuel return line...

I verified this with my Ranger via VIN (OHV have an X code, SOHC has an E... my VIN does not have an E, but does have an X), so that means this vehicle is set up for the lower PSI, but the engine in it is not getting what it needs.

Uuuurrrrggghh!! This vehicle is such a pain in the butt... I really don't know why that mechanic didn't just rebuild the engine vs putting in an entire new one, he should've researched this. I'm really tempted to call the guy who put it in, even though it's been 3 years, and give him a piece of my mind. *sigh*

Suggestions? Do you think we can do away with the fuel return line and still put the 2006 pump in?

 

Accordind to my Haynes all engines after 97 have the same higher pressure and no return line. The only exception is the 3.0 flex fuel which has a little lower pressure but still no return line. I will check later when I get home. Remeber the truck ran fine for a year
