what up ht members. i gotta a hybrid motor in my 95 dc2. it's kind of a makeshift car right now until i find everything. but here's the problem. the fuel pressure won't go lower than 50 psi on my fuel pressure regulater gauge.
the motor is.......
b18 head.....b16a block....p73 pistons.

everything works great...vtec kicks in hard, revs up good. it just runs really rich. is that normal?

oh yeah. and it puts out the engine code 43. what's that???? i heard fuel system.

thanks guys.

 

code: 43 Fuel supply system
next time make sure to look at the very top of the forum and you'll see "ECU and ABS CODES HERE!" click there.

 

Or you can get a fuel pressure regulator..

B&M will do you nice. $30.

 

uh, he has a regulator

 

Uh he mentioned, fuel pressure regulator gauge.

I'm thinking he probably meant the gauge on top of the fuel filter.

Like the one I have on my car...

(located on the right corner of the picture)


AND the B&M fuel pressure regulator is adjustable. Different from a fuel pressure gauge.

Uh ok?

 

okay...but no answers???? ttt

 

i can't adjust it under 50 psi. it's turned all the way. it was at 65 psi when i first installed the regulator. adjusted it down to 50. won't go n e lower. is that normal?

 

Stock fuel pump?

 

What kind of fuel pump?

Aftermarket pump (like Walbro 255) with B&M regulator = can't lower below like 50. In order to do so you have to modify the regulator. There's instructions somewhere around here on how to do it. Basically it's just drilling a small hole towards the return line inside the FPR (hard to explain.. do a search for it.. i gotta go to sleep... gotta wake up at 3 lol)

 

looks like a stock fuel pump. no weird stamping or n e thing. just some numbers. no name brand.

 

ttt. can someone help??? it don't pass smog either.

 

trust me i've checked just about everything you can check. puzzled...

 

Why don't you find someone who can provide you a stock fuel pump first. Since you are unsure about yours.


See the link in my sig...i was out with my newly boosted car for 2 weeks and I didn't realize it was the new Walbro (2 days old)! But I had an opposite effect, mine just went out and causing me to have 14psi of pressure.

I wanna boost 50 psi!

dude did you read the original post he's talking about fuel pressure, not forced induction.

Maybe he read my post and saw the word, "boosted".


EVEN SO...

That's funny *** **** right there.

 

man u guys are funny. everyone gets so confused on here sometimes. okay here are some other things too. after i take her to redline like 2 or more times in a row from first thru 3rd....the idle stays really high too. like at 2000 rpm and doesn't drop again until after i drive around normally for a while. is that the throttle body staying open or is the engine still getting fuel after i let off? and when i rev, the fuel pressure drops to like 45 psi instead of rising. isn't it supposed to rise when you rev? one more thing too...can the head and block combo i have be causing this? i highly doubt it. what about the o2 sensor? can that affect n e thing at all??

 

Hmmmm sounds like a vacuum leak or one of the vacuum hoses.

And you are correct about the fuel pressure increasing if you rev even at idle. If it doesn't increase and drops instead...this would be bad at WOT and will caust detonation at high RPMS. You are lucky you aren't even turboed, else it will go boom!....

Ok not so much as a boom but you get the idea.

I'm advising you. Switch out your fuel pump from another car, preferrably another Integra.

 

First thing is to make sure the vacuum line that goes to the FPR is not kinked or damaged.

Try this, with the engine running pull the vacuum line off the FPR. Fuel pressure should increase and go to maximum.

 

well i've done that too. the pressure has no change whether it's plugged up or not.

 

okay. i forgot to mention the extra nipple on the intake manifold. it's on the driver side port i guess if that sounds right? if you're lookin at the car then the xtra nipple is on the far right of the intake mani. it was plugged up but still leaking air. now it's plugged up better and the psi is down to 40psi. but it's still adjusted all the way down. it goes up very little when i rev now, and barely goes up at all when i unplug the vacuum hose. and when i plug up the vacuum hose with my finger it goes down a little too like back to 40 psi. my buddies gsr goes up a lot when he revs. he's set at like 44-45psi. when he revs it goes up quite a lot. when he unplugs the vacuum hose it goes up a lot to like 60 or so. and when you plug up the line with your finger it does nothing. psi stays high like when you first unplug it. and i'm assuming that's normal cuz his gsr runs really good. i drove it at famosa and hit a 15.37 with just an intake and fpr. and his car passes smog no problem too. so now what? what else can i do? new intake manifold?

 

yo ur bro said u might be interested in a gsr manifold?
