dude that would be great....let me just see if i can get this thing running today...if not then yea ill def get back to you for next saturday

 

aiite sounds good, lemme know

 

hey im like 20 minutes from tewksbury myself. i might swing by to. see if i could lend a hand

 

WOW I NEED HELP

I AINT TOUCHIN THAT DAMN CAR UNTIL I GET SOMEONE HERE LOL

now i got it started and its friggin spittin fuel outta the injector

which is weird cuz i thought that injector that shows right under the UIM is a secondary and it even spits as im starting the car?

 

The injectors under the UIM are the primary injectors. The Secondary injectors are the ones on top of the UIM. If they are spitting fuel out through the top of the injectors, then your o-rings are leaking and that could easily cause no start or hard start issues. Could even allow the engine to run on only one rotor.

Its easy to replace the o-rings but you need to be careful when installing the injectors. Place a little bit of oil on the injector o-ring and slowly work em in to the fuel rail. They tear easier then paper.

Getting down to the injectors is the time consuming part and confusing part if you have not done it before.

Fuel is always flowing through the fuel lines that lead to the secondary injectors as well. Just a FYI. The injectors don't energize untill around 3850 rpm depending on load.

 

its not my primaries

its my secondaries and its not from the top of the injector its from the bottom of the injector

 

huh?

The secondaries on top of the UIM are spitting fuel out from the bottom?

From your description it sounds like the primaries. Secondaries do not energize while under 3850rpm.

I would suggest your grommets but there is not reason for the fuel to spray through the grommets since there is no pressure in the intake manifold at idle or at all with a n/a.

 

no its my secondaries i kno what im seeing......

and my car is no n/a its a T2

so i do believe it is my grommets....hopefully like advance auto parts or autozone carries them

 

Ah T2. That would explain the location of them.

Even if the injectors are operating and if the grommets are bad, you still shouldn't see fuel being sprayed up. I dunno, advnace does sell grommets and orings.

 

i dunno wtf is goin on lol.....it def could be the grommets tho...they arent sealing enuf soo as the injector is spraying its squeezing out the sides...but should it really be spraying that much...unless something is clogged where they sit but i cant really see anything

 

heh sounds like your having fun, im still figuring out this weekend so hopefully ill be up there, lemme know whats going on

 

im available on friday to take a look at your rx i live near by. i cant do it tonite i have forgeins car to get up and running.

 

Max, can you datalog with your wideband?

 

no not yet but soon. i have a 32 channel data aquisition computer. i have an FJO wideband laying around somewhere tho.

 

Dude, there aren't ANY injectors on the UIM....

 

For some reason, DUDE, I was thinking he had a Non Turbo. Not a turbo. That was my mistake.

Let me know when you can. I would like to dial in my AFR pretty good some day.

 

Sorry Dude.

 

sure ill let ya know i just need a few more components and then load the software.

 

i am right outside of worcester

 

problem is fixedddd finallyy!!

thanks for the help guys

now i just gotta get the damn thing tunedd...i gotta get a wideband

 

So what was it?

 

Dudeeeeeeeeeeee.

Chill out guys. Friend of FRFC3S must not fight friend of FRFC3S.

RX7 shall not kill RX7.

 

rota u were right...it was the O ring...my friend said it was leaking from the bottom but wen i checked it was the top...soo then i knew u were right...thankss

i do believe im runnin rich tho...cuz my car smells like gas and i kno im not leaking anything anymore....smellsss sooo bad..unless its just cuz its a new engine but i doubt it

 

not to mention i have no clue on how to use this SAFC....came wit the car so.lol....and i dont have a wideband :-/

 

Is the SAFC's corrections set to anything? I wonder if someone set the SAFC to inject to much fuel. Although, if its SAFC 1, it shouldn't effect idle, but if its SAFC 2, you can adjust down to 800rpm like I do.

If you have a S4, you can adjust the idle AFR. If its a S5, you can't unless you have a SAFC2 (not 1)
Here is a howto on how to adjust the idle and idle AFR

This is why I don't listen to my friends anymore. Most of the time, they have no idea what they are talking about. They call them selfs car guys, but they don't know why you need a wideband to do a proper tune and think narrow band o2 gauges are worthless
