still not right

[bruiser]

ok so if i have te truck parked it starts up and runs perfect but once i back it out and go to take off it as no balls it has sat for awhile so im going to change the fuel filter and fuel to see what tat will do but after tat i have no idea what to do if tat doesn't do the trick what do ya'll think :idea:

[Jesshwarren]

Are you running tunning on it yet?

[RebelRanger97]

Have you changed your fuel pump yet ?

[bruiser]

no its not tuned...its stock none turbo stock injectors stock everything
and the fuel pump has good pressure

[nagelandy55]

when you say no balls what do you mean? Can you boost at all?

[bruiser]

its not turboed....

[bruiser]

ok so i drained the old fuel and replaced it with new fuel and it ruins a whole lot better not quite what it use to be but a lot better than it was i think once i run out all the old fuel it will be pretty solid what do y'all think?

[Jesshwarren]

Low compression pistons may cause a little HP loss when naturally aspirated.

[bruiser]

yes but it bogs down upon take off and doesn't wanna go over about 55mph ill take a video and show ya'll

[AJ_Fritz]

ok enough of the confusion. is this a turbo pistoned motor your running N/A? or is this a stock N/A 2.3?

[bruiser]

this is a 2.5L converted to a forged 2.3L N/A

[nagelandy55]

Well the computer thinks its a 2.5 but its really a lower compression 2.3. That is most likely your issue.

But could it be getting too much fuel because of this?

Try putting a 2.3l computer in it and see if that fixes the issue ..... i have one kicken around if you'd like it.

[AJ_Fritz]

i think its the low compression. how much static compression does it have now?

[flyin]

Just for reference sake my header cracked last winter so bad that I could not make ANY boost. I was running a 2.3 at 8.0-1 compression with the turbo tunning and it ran pretty much similar to how it felt before. 75 was hard to maintain on the freeway in fifth gear so the difference that you are feeling shouldn't be from compression only.

thats what i was thinking but the 2.5 and 2.3 are so much alike thos wouldnt it just read the sensors???

but how much would you want for the 2.3 ECU??

[nagelandy55]

shipping .... i just want to get rid of the damn thing, its out of a 96 though. I have a 98 computer in my 96 and it works fine just not sure if it would work the other way around.

[salating]

the only way i could see problems if the wiring is different

it may be since its a different gen ranger but who knows

chances are it will work i would think, cant hurt to try it out

[bruiser]

the only thing i can do is try...is it for a standard tranny?
i think since its obdII it should work i think not sure tho but it would have to be for a manual tranny

[nagelandy55]

Yep its for a stick. Pm me if you want it.

['97-2.3L-ranger]

i have a stock 2.3L pcm (cys2) i'm not useing. i changed to a flh2. it was off a 97. what pcm code do you have?

[bruiser]

ok so i tried swapping out my fuel pump out to see if it would help but...It didn't very much so im gonna try the 2.3L PCM and if that doesn't work im selling it and buying another bike

[bruiser]

well today i towed my truck up to my job to see what the other guys could think of that it might be well we found the cam timing was off by one tooth which now it starts up and idels perfect....but it still...when i go to drive it it bogs down...i have now changed my fuel pump..filter and one injector so i dk what else it could be its not the cat becuase i drove it today with out one to see if that was the problem...but of course it was not...so does anyone have any clue as to what im either doing wrong or what would be causing this???
anything will help

thanks clayton

[nagelandy55]

Going lean or boost leak?

[bruiser]

its not turboed yet this is a 2.5L-forged 2.3L engine N/A

[Jesshwarren]

If you could hook up a wideban o2 sensor see if you got a lean or rich cond.

On a side note you will not have as much HP with the low comp pistons running N/A I noticed a big gain in HP when I went to laeger injectors running N/A. I was stumped but stock they run a lil on the leaner side.

[bruiser]

so you think i should put the larger injectors in??
but i mean it feels like a i have 50hp its really weak...im completely stumped I've done everything replaced O2 sensors installed a new fuel pump replaced the fuel filter I checked to see if the cat was plugged but it wasn't I fixed the timing problem it's just a never ending list and honestly im getting tired of it...getting ready to get rid of it mainly cuz i need something to drive around beside the POS jeep i have.

[fordnut71]

id say you have more like 88 hp as thats all the mid 80s 2.3l n/a put out. also if you have your 46.5 # injectors in there its prob running a bit rich so youll have to put in the stock 15# injectors while its n/a. fuel pump should be ok
also check your mass air isnt dirty on the elements. a few shots of brake cleaner is all it needs to clean them up.

[bruiser]

i have stock injectors in i was told to check the maf and map sensor the the TPS soo ill see whats up after that and its not a mid 80's its forge bottom end 99 2.3l DP head

[PrerunningRanger]

well what it sounds like is you need to turbo it because the N/A with forged bottom end is what seems to be holding up the power... you have no compression with means you got no power... im sure once you turbo it it will run right, but seriously it sounds like thats your problem..

[Jesshwarren]

i have stock injectors in i was told to check the maf and map sensor the the TPS soo ill see whats up after that and its not a mid 80's its forge bottom end 99 2.3l DP head

Scan it fore codes. If anything is wrong it should throw a code.

[bruiser]

there are no codes.=(

[bruiser]

well what it sounds like is you need to turbo it because the N/A with forged bottom end is what seems to be holding up the power... you have no compression with means you got no power... im sure once you turbo it it will run right, but seriously it sounds like thats your problem..

im sry thats the worst thing i've head there has to be a reason it BOGS while accelerating a turbo right now will make it worse if anything and plus i dont have the chunk of change to toss at it right now deff. not now if it's not running right with out a turbo

[fordnut71]

well what im trying to explain to you is that the internals are like a mid 80s 2.3l low commpression motor. (i understood its a 99 motor u using)so it should only make about 88hp. the turbo was bolted on an gave it 145hp.this is mostly factory specks. so im taking you have the 99 2.5 35# injectors in there witch would give you to much fuel causing a bog an sputter. so u need a lower # injector in n/a form to lean it out. so look for a 90-93 mustang with a 2.3 d/p head an use thos injectors.

[muddpawz]

did it ever run correctly after swapping in the new turbo internals? Or did this occour before the internals were swapped? Im with fordnut, sounds like its gettinng too much fuel, and until the higher rpms cant burn it all?

[bruiser]

ok that makes sense but how would i test that...and also as long as my comp is reading the sensors right it should give it the correct amount of fuel and air correct?

[fordnut71]

well yes in a way the computer is trying to give the right fuel/air mix but if the injector is to big for the motor the computer will just run like crap. its like running a motor too lean, not enough injector it will run like crap an break up. this is the oppsite so its to rich an bogging. so the only way to make it run right is with a smaller injector.
a 91 mustang with a 2.3 d/p head is like 90hp an a 95+ ranger 2.3 d/p has a rating 122hp.the mustang will use a smaller injector an the ranger uses a bigger injector. both stock.

[bruiser]

Well if that's the deal could I just get thecopm tuned? Wouldn't I have toanyways if I put in a smaller injectors?

[bruiser]

do you think the timing will be off since i swaped to a 2.3? so the marks on the block of my truck will not be right for the 2.3 timing???

[D94R]

This thread was lacking info from the get go, and quite frankly, with Bruisers post, and others, I'm lost as to what your setup is.


You are using a Ranger computer?
You are using the Ranger injectors?
You have a 2.5l block with 2.3L internals, and forged lower compression pistons?



And the timing for the 2.3 and 2.5 are the same. No difference.

[nagelandy55]

This thread was lacking info from the get go, and quite frankly, with Bruisers post, and others, I'm lost as to what your setup is.


Ya i've been lost from day one with your setup. Make us a list of stuff your currently running, not stuff your going to run or stuff you have in your basement.

It can't be anything to complicated, we just need the right information to steer you in the right direction.

[Jesshwarren]

The best thing to do would be check codes, do some data logging also. Do you have a xcal-2 or 3.

[bruiser]

ok to clear it all up

stock ranger ECU
stock 2.5l Fuel injectors
2.5L block with forged 2.3 internals
255lph fuel pump

i dont know what else you want to know
but i think thats the basics

the problem is when i go to drive my truck it bogs down really bad it takes and 30 sec or more to get to 55mph it does get up to speed but its really weak and lacking lots of power

[nagelandy55]

Ok thats better, clear as a bell now.

My guesses would be its your lower compression and the 0.2L less displacement screwing with things. Otherwise everything should work fine.

[bruiser]

ok so you think getting the smaller injectors and use the 2.3L ECU???

[nagelandy55]

best thing would be to hook up a wideband and see whats going on. I can't see what smaller injectors would help unless the 2.3's had smaller injectors than the 2.5's.

[muddpawz]

make it easy and get an old turbo header and generic turbo, and give 'er what it needs...boost!! lol, Nah sounds like data logging would be the end of all your guessing troubles. Hang in there and dont give up yet, its a hobby, and after all just a mahine with basic needs!

[fordnut71]

thats the basics of what he has is a older 2.3n/a so it would be a smaller injector.
the closest thing would be the old 2.3 d/p 91-93 mustang.

[nagelandy55]

I doubt the injectors changed between the 97 and 98's. He doesn't have anything like a 91-93, he's using the OBDII system from the 2.5 with forged internals. The only difference between his engine now and his engine before is the lower compression ratio and possibly oversized injectors but i doubt it. I wonder if jess knows what injectors where in his 2.5 stock, that would settle this confusion.

[nagelandy55]

From what i found they are either 14# and 15#

[Soul]

Um do you have dished pistons and NO compression cuz 8:1 is a pooch
?

oh you have no idea how bad i would like to do this but as a college student and broke as much is my truck is its a little difficult im not far away from it tho i have the turbo larger injectors and xcal which i need to get unlocked i have the e6 header which i would like jess's header so i can keep A/C all i need now is IC piping and the oil lines i guess and a tune then i could boost it but now i would just like to get it running right if i cant get it running N?A how do you expect me to get it running turboed? and i believ the 2.3l had 19# injectors

[fordnut71]

5.0 had #19 injectors

[Jesshwarren]

I am not sure what injectors the 2.5L ran. However the 2.5L ECU is programed to run a return less fuel system that runs a rail pressure of 65PSI.

If you are running a return rail at 43 psi and the 98 2.5L ECU you are lacking fuel in a real big way. What do you have on it now for a fuel system, 98 ranger injectors intake and ECU?

I'm not quit sure i understand what your saying. so you think my rail pressure could be low??
im not really sure how because i replaced the fuel filter and the fuel pump so you think injectors are bad? and yes i have a 99 2.5 injectors and PCM

[D94R]

What he's saying is the 2.5L injectors are rated to flow X amount at 65psi rail pressure at a given RPM and load on the engine with the returnless system.

If you have a return style swapped in for the turbo swap, and you have the stock return style pressure to the rail, which is 40ish psi you are not flowing enough pressure at the same RPM and load that the ECU is trying to command.

Make sense?




Also, have you checked the basics? Base timing? Cam timing? Coils? Plug gap? etc?

[bruiser]

Ok now that make sense but I didn't switch the fuel rail and I have checked the basics multiple time too monday I'm taking it to school to check pids and see what's not right

[Jesshwarren]

OK here is where I think your problem is! Check your fuel pressure. You installed a 255LPH pump. The 98 and up returnless systems have a 63-65PSI regulator in the tank on the sending unit, with the 255LPH pump something may have gotten messed check your fuel rail psi.

[bruiser]

ok so today i had my truck up at the school and we were checking the pids and found out my maf is getting high voltage it was getting like 1.5v at idle and reading like 7.00g/m basically it was way over spec at that spec i should be at 35mph so everything is out of wack gonna try to clean it and if that dosen't work replace it hope it works o and we checked my Fuel pulse width it was a little high but i think it cuased by the faulty MAF

[nagelandy55]

You shouldn't be pegging the stock maf. Let us know if the cleaning helps any.

[bruiser]

cleaning did not help but it was really dirty from sitting so long and it could have been a faulty sensor not saying im pegging litteraly but its read like it is but i got a new one and ill see what happens later today

[bruiser]

ok so the maf helped but did not fix it completly i retest the fuel pressure and it seems like i have a pressure leak in the tank sooo the pump is new what else could it be back there?

[fordnut71]

maybe you have a crack in the rubber line that connects the pump to the steel line. also the hose clamp could be lose.

[bruiser]

all the lines are good i checked do our trucks have a regulator in the tank and one the rail?? maybe the one in the tank is bad

[bruiser]

what type of fuel system do the 992.5l rangers have?
Mechanical Returnless or Electronic Returnless or returnable system??
