I recently put a GSR engine in my VX hatch.. and it still have the VX fuel pump in it and im running rich.. Do you guys think if i put the GSR pump in it will fix the prob? It never ran rich when it was in my teg.. so i assume this could be the prob.. I'm gonna change the pump soon anyway.. but im just wondering if this could cause the prob.. TIA guys

tinkerbell

what makes you think you are running rich?

umm....if anything you would be running LEAN now, not rich.

It's not a fuel pump issue if you're sure you're running rich and you're using the stock VX pump.

I had it checked.. I'm running at 5 - 9 psi over what i should be. And im throwing the RICH code... And since im using the wrong fuel pump it could cause the opposite of what you guys think. It could try to compensate for the fuel the engine needs.. and, because of that, give TOO much fuel. We will see when i change the pump.. Like i said.. When the engine was in my GSR with my GSR fuel pump, it was running fine.. No codes. At least now i have a good excuse to put the gsr pump in.. i can run at optimal now!

I am having the same problem, I have a gsr in my civic coupe ex, And I got a check engine light, so I took it to autozone for the free diagnostics test and it gave a code of "too rich". I'm running the stock fuel pump, so maybe if I put a gsr fuel pump in it will fix it.

Well, i'll let ya know how it goes for me. I'm prolly gonna put the pump in on saturday.

Did you guys use the GSR or Civic regulators on the fuel rail??

johnzm

guys the fuel pump only send fuel to the rail. the regulatr tells it how much pressure to leave there for the injectors to use.

a good rule of thumb that both and I and all my friends use for hyrbid cars with codes is this. If you get a code, reset the ecu and see if you get it again. On bs codes like emissions, or fuel enrichment it is good to use. I would suggest resetting the car and seeing if you get it again. You might have run rich for a couple of seconds, just long enough to throw the code. I wouldn't suggest taking this method with something serious like knock sensor, but for emissions codes and fuel richness codes it won't hurt.

We have reset the the ecu and i still throw the code. And when i had my exhaust custom bent, i also had the guy run a test to see what psi they were runnin, cuz i knew i was runnin rich.. and he said it was a constant 5 - 9 psi over... I dunno.. I'm just gonna see once i change the pump! Thanx guys, more opinions are welcome!

I changed the pump today and took her out for a test run. I was out for about 20 - 30 minutes.. I ran her pretty hard just tempting her to throw that code.. But nothing! I need to do a lil more investigating.. but i redlined the crap out of her gears and usually when i do that 4 or 5 times she throws the code. I'll keep you guys posted. I need to race my friend soon.. Last time we went out i threw the code within 5 minutes.

tinkerbell

but dont you understand?

it will never thow the code if you are trying to make it throw the code...

t..

Hatchy-Ownzjo0

It's soo tru.. I'll just think i solved the prob till it throws the code again!

TTT Let us know if it pops up again. I'm currently battling a code 45 (too lean or rich) and am thinking that it's because of the pump. I'm using the stock DX pump on a b18c5.

Hatchy-Ownzjo0

Since i changed the pump i have thrown one code.. and it was this friday that i threw it.. I have not checked to see what code it is yet cuz im lazy.. but once i get around to it i'll let ya know if its still runnin rich.. but i think it is cuz i filled up yesterday and i only got 22.4 mpg.. But thats after a night of some hard core driving.. So im not sure at this point..

StolenSi

Yea, an update would be cool. I know my code 45 could be caused by so many different things but eliminating each possibility one at a time is the only way to effectively troubleshoot. The cost of an ITR fuel pump or new O2 sensors kind of makes me want to be sure that they could be causing it, before going ahead and buying them.

Good luck on your end BTW!

Hey Hatchy-Ownzjo0, what code did you get. I'm asking b/c my B18c1 is running rich in my Ex and I want to know if changeing the fuel pump to a GSR one help's.

96ek

Does anyone have anymore information to post with regards to this as i am experiencing the same problem on my 96cx bith b16a2 7 stcok pump. (for some reason only lately in the last 2 weeks or so)

Please keep us up to date with your findings

Thanks in advance

Hatchy-Ownzjo0

Still have not got around to checking the code.. I'll do it some point soon i think.. im one lazy kid!

96ek

Keep us posted!! i really need to know as i will be getting the SI/SIR fuel pump installed today.

Thanks

Hatchy-Ownzjo0

Sorry it took me so long guys.. but i am NOT runnin rich.. I have a bad O2 sensor.. so looks like i get to shell out some major $$$ to fix this prob.. I might just go up to a jumk yard and pick up a new one.. But i have been getting no better than 24 mpg recently.. i should be getting closer if not more than 30.. but this explains it!

StolenSi

hmmmmm. I have to get around to checking my damn O2, especially after reading this. I know recently my gas mileage has dropped significantly, with no driving technique changes.

Since I've dropped my fuel pressure (last weekend), code 45 hasn't come back on and my mileage has been slowly going up from 20mpg, back to around 25. I still think I need an ITR feul pump and possibly a new O2 but I'll leave it alone until a code gets thrown again. DAMN OBD2!

Hatchy-Ownzjo0

That is what my mileage has been doing.. i checked it once.. and it was 21.5 then it went up to 22.5 and last time i checked it it was at 23.9.. thats still pretty shitty.. but i now know its cuz my damn o2 sensor.. pos.. thats like 200 bucs from the dealer too.. how gay!
