im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

i havent started my turbo b18b turbo civic for a good week since i was somewhat on vacation

here's my set up

b18b
arp rod bolts
ported/polish head
jg mani/itr tb

turbo set
t3/t4 turbo
drag mani/2.5" dp/ 2.5" striaght pipe etc
440rc/crome tunned


when i got back home, i wanted to warm up my car then go pick up my girl
it started fine the first time.. and held idle very low, around 400-500rpms
then when i try to give it a little gas, rpm's goes up VERY slow even at FT i could barely try to get it to 3k's rpm's like if it was running on 2-3 cycl, it would barely move.. i turned the car off, and tried to turn it on again.. this time.. it just cranked and cranked and wont turn on anymore.

im stomped.... i cant figure it out..

there was no CEL, so i really didnt know where to start...
first i thought it could possibly a bad map sensor, i had an extra one so i swithced it and gave it a try.
same car just cranked and cranked wont start anymore.

i then checked the voltage for both map and tps.. both are to specs. so i know they're good.

car is getting fuel...
40psi on my b&m guage/str rail/new fuel filter/255lph walbro

i checked the timing belt/cam timing.. looks good. timing is good

pulled the plugs out, slapped a screw driver in and held it to chassi to see if it gets sparks..
and it did on all 4 cycl

so then i thought it could be worse so i...
did a compression test, i got great numbers across at 170across COLD
BTW, i took the 15 fuse from the engine bay ECU fuse (so it wont hurt my dizzy)

then i looked at the spark plugs.. they look normal, but smelled like gas, i then cleaned them up and put them back in, gapped at .28 with bkr7es..

checked all the fuses once again, underdash/engine bay to see if there was any blown fuse IE Ignition etc..
NONE

i re checked all vacum lines/wires/etc etc... nothing seem abnormal..

car ran fine before i locked it up in the garaged before i left
im stomped and i really dont know what the problem could be...

any help or any imputs would be nice

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

Ok...so you're getting spark and fuel...for sure? The sparks smelling like fuel = injectors work? If it started at all, or made an effort to turn over, a silly problem could be the FITV bieng closed all the way...I think not...Ill think about it and get back to you, bored as ---- in study hall man, good luck.

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

i think you mean stumped, not stomped, if your stomped you've got a whole new set of problems...

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

Has this car run good before, with the same setup? Has it been tuned at all?

Get a wideband on that thing. Sounds to me like you got way too much fuel going in.

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

my guess would be an injector is stuck open

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

the car is tunned. and car was running perfectly fine before.

FITV, i dont think i have that on my trottle body.

im not sure how to tell if the injectors are stuck open or not, i somewhat think they are though. because when i crank it, it almost starts the car up, but then it fells like it chokes and dies. and then it keeps on turning over and over...

=/ anyone?

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

im going to tell my friend to come over
he has a 95 integra ls, obd-1 stock
so im going to swith to stock injectors and stock ecu and see if it would crank over and start
i wont be doing this till tommorow since he said he's getting off work real late today

any imputs??

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

my friend had a similar issue with his acord was geting spark and the car would run for a while the it cut out. turned out the distributor was dead. cheap fix. Just a thought

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

I Had The Same With My Gsr Try Unplugging The Ecu For 30 Seconds Then Plug It Back In What Ecu Are U Running

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

have you checked to see if you have a loose rotor button?

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

im going to open up the distrubutor to see if the rotor is loose or something
yes, ive unpluged the ecu for several minutes.. then tried.. same thing
before i put stock injectors back in wiht stock ecu.. im going to try to figure out whats wronge.
btw, im running a chipped p75 on crome, obd-1

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

i finally got the car to start,
i put in stock injectors, and stock ecu..
car idles great and run smooth without any CEL staying out of boost ofchorse.
so it was because of the injectors..
could somebody please explain to me why though? and are my RC440 injectors not usable anymore? what was the problem?

thanks everyone who helped

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

I would definately contact RC if they are pretty new

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

yeah i tried earlier to reach them, but they are closed after 5pm, and i called at 6pm..
ill try tommorow and see what they could do for me.

Re: im stomped... new problem!! help!! rough idle/wont start/tried everything!!
 

yeah ill have to send them to RC, $25 each =/
i dont have the receipts, but its been too long anyways

i put them back on my car, and the car started up perfectly fine again with the tuned ls ecu... what the hell? i mean... i cant have my car not starting when i need it to start... injetors are perfectly fine? can someone please explain to me why it was stuck open last time?
