Got #2 cylinder running, now 3 wont run and im running rich as hail

[JJ Alfano]

im running so rich gas is coming out of tail pipe...this is new to me, just happened just now, swapped #2 injector back to the old one (s13 obd1) thought maybe the resistance in the obd2 s14 might be a tad higher causing not enough fuel burn, cranked her up, still running on 3 cylinders...so i pulled the spark plug on cylinder #2 and the car almsot died!! (which is good cause now its firing) But now cylinder #3 is doing the same crap that cylinder #2 used to do! and now i got unburnt fuel and loads of white smoke outta my tailpipe!!

whats the dealio?

its obvious im running rich, but why? leaky injector...bad rubber washer..let me knowwwwww!!!

[Zippy69]

What's been done to the engine?

[JJ Alfano]

..nothing? i swapped it, had ignition issues with cylinder #2 from the start, diagnosed it, swapped it twice, got new plugs, and tried again, started running, but now cylinder #3 isnt working and im throwing gas outta the exhaust. I have 175psi across the board so compression is gooooood


i get 12 volts from all injector wires :goodjob:

[Subu]

I would like to see the reason as to why this is happening...I get to learn a little more. Dave should know something about this.

[Zippy69]

What codes is your ecu throwing? If something is f'ed up, then your ecu will go into safe mode. It will run rich to make sure you don't lean out and blow your engine. it will run like shit but it will run enough to get you home or to a repair shop.

[JJ Alfano]

this is not "safety rich" this is "WHAT THE HELL IS GOING ON WHY IS THERE RAW MOTHERFUCKING FUEL COMING OUT OF MY EXHAUST PIPE...rich"

[Zippy69]

Damn. You must have a stuck injector or something. Have you had it to run right at all?
I have a set of dohc injectors.
Check the orings. Pull the rail (only 3 bolts) and then check each injectors orings.
If they are messed up, it will pour fuel right into the cylinders.

[JJ Alfano]

im thinking thats what it is, gonna swap the #3 injector tomorrow in the daylight, hopefully that will work

does anyone have the resistance ratings for obd1 s13 injectors, and obd2 s14 injectors..any difference? after i swapped out the s14 the cylinder worked...maybe its just a miracle?

[Zippy69]

Good luck. I don't think there is a difference between injectors, but I may be wrong.

[Z U L8R]

i responded on importatlanta
Dave

[v-empire]

jj, call viperblah

you two should mate :)


this is a stock motor you speak of?
so no spark on numero 3...blown head gasket?
what did you do to the motor and where did you get it?

[JJ Alfano]

i bought it from krappy, 175 psi on all 4 cylinders when i did the compression test, no psi leaks, tested all injector wires and got 12 volts, the cylinder was just running, so what im thinking is when i inspected the injector i damaged the o-ring, causing it to leak and now its getting too much gas and not firing, gonna replace the injector tomorrow and hope for the best!

[JJ Alfano]

UPDATE: All injectors are making a ticking sound when i use a screwdriver to listen, running rich as hell, but now both 2 & 3 arent firing. No raw fuel is coming out, but still white smoke. Recap: 12 volts, and good ground, brand new plugs. Good compression. Going to swap wires, but i dont think it will make that big of a difference.

[Zippy69]

If there is too much fuel, they won't fire. Did you pull the fuel rail like I said?
I had the same problem when I first turbo'ed mine. My 550cc injectors were pouring fuel in so fast, that it was drowning out the plugs. Mine was an ecu issue but, the same concept applies. Pull the fuel rail and see if the injectors either leak through their orifice or around their body when you turn on the key.

[Blake]

someone help please jj needs it done before the 16th

[Zippy69]

Trying to help. The only way to tell is to pull the fuel rail with injectors intact and test that way. Most likely it is o rings. Just install a new set with a good o ring lube. Not oil or grease as they will deteriorate the rubber.

[Blake]

yeah everyone has been looking at it its just like one thing after another happens
but im going to go over there later on today i think ill try that for him

[seksehowy]

BLAKE!!!! YOU MISSED the party tonight man wth!! JJ IS like crashed over on where andrew shoot airplanes every night, nasty ass shitt. damn u missed it big time, freal everyone was freaken there except your gay whtie ass :\

shit i fell asleep waiting on steve to come pick me up
but im porbably buying a motor from tyler today or tomorrow

[JJ Alfano]

i popped out the fuel rail, and had my dad turn the key but not start the motor to my expectation, 1 and 4 dont leak, but 2 and 3 are alllllll over the place

where can i get another set of o-rings, autozone didnt have it, im gonna try advanced here in a minute (gotta look in the phone book) i was just gonna replace the injectors for time reasons, but my s14 fuel rail, those damn screws are stripped...i hate how every metal on a 240 gets soft after 20 years its GAY

[Zippy69]

Glad you found the problem. Most parts stores should have them. Is there an O reilly's near?

[JJ Alfano]

swapped the injectors, now all 4 cylinders are firing, have no smoke coming out

but im boggy as hell, i sound like im running on 3 cylinders, but when i do the spark plug check all 4 kill the motor, whats the deal?

[Zippy69]

Did you check your plugs? Can you drive it? Also check your oil for fuel. Go ahead and change it before you do some damage.

[JJ Alfano]

plugs are still a little sooty from when i was running rich, ill scrape off the soot and run the plugs for a couple

talked to dave, thinks it may be my timing, ill double check that and get back to you guys, ill check the oil as well.

[Zippy69]

Good luck man, I know this kinda crap can be annoying. I spent 3 days trying to figure mine out.

That sounds like plugs, timing or maf. Deff check plugs first since you probably fouled them out running so rich before.

i put it at 20* BTDC the car cranks up, but the car is very boggy when gassing it and i can hear the vacuum leak and it dies almost immediately after i start it

give the youtube vid some time to come together

[Zippy69]

That was the drift video. I already said I liked it.

[JJ Alfano]

look at the link again i fixed it

that video is almost pointless cause he kept revving it so much...i told him to give it enough to keep it alive, and you can hear him rev all the way past 5 grand...

[Zippy69]

That does sound like a serious vac leak.
Can you give me a run down on the engine from start to now? Everything you've done.
Last time it was running right, parts swapped etc.
What codes from ecu?

[JJ Alfano]

i do need to check ecu, will do in the morning

this is a new motor swap, hasnt run right since i put it in.

s13 obd1 intake manifold, #1 and #4 injector are obd1 s13, #2, and #3 are obd2 s14 injectors, distributer is from s13, wiring harness is s13, maf is s13 etc.

basically its a 97 obd2 motor turned obd1 and put into an s13.

when i first got the car cranked, i had #2 cylinder not firing, swapped wires, plugs, dizzy cap still didnt fire, just now got the injectors replaced (it was the orings, but was easier just to replace the injectors themselves)

after that all 4 cylinders run, but the power feels (and the motor sounds) like im only running 3 cylinders. the idle (whenever it was staying alive) would bounce from 1200 to 2000 off and on, and the vacuum sound is loud as HELL! The alternator belt has frayed sides from damage (recent also) so thats that loud squeak on acceleration (thats the least of my worries right now lol) so my guess is since the timing should be correct, that the vacuum is causing all these problems...but i cant keep the car idling long enough to find it, i was gonna do the carb cleaner trick and just spray every rubber hose one by one and see which one make the motor idle right. i thought about using a smoke machine to see where air is being sucked in but no one around me has one!! HELP!

[Zippy69]

Before you pull the codes from ecu, have the ecu set so you can see the red led from the drivers seat. When you tun the key on the light should come on. When you start the car the light should go out. If it stays lit, there is a communication problem somewhere.
Which maf are you using?
Did you test the injectors like I said? Not trying to hound you but If your not 100% sure the injectors aren't leaking by, then it will be even harder to figure out.

[JJ Alfano]

i did the injector test, thats why i replaced #2 and #3 :goodjob:


ill check the ecu tomorrow in daylight see if i can pick up any codes

also, anyone have a non confusing write up on how to check codes plz thx

[Zippy69]

Codes are easy as turning a screw. The screw on your ecu, you'll see it when you see the red led.. Turn your ignition on, turn the screw all the way ccw and wait 2 seconds, then turn it all the way cw. The led will flash the codes. The first flash will be slow and thats the first number in the code, then it will flash fast, and that is the second number.
flash flash flash =3 blip blip blip blip = 4 Code 34
It may flash several codes, but it will keep repeating it over and over so you don't have to freak out if you miss it the first time.
you will find it easy once you do it.
Once your done reading codes, simply turn the screw ccw and then back again to reset it.
