4th gen Civic hatch, B16a
i have a 1990 si hatch with a b16a from an SiR in it...im having some problems with vacuum lines, i have the diagram but i cannot figure out what to to about the missing fuel pressure regulator cut off solenoid...
we've had some nice 35 degrees C days here, nice and hot...and my car does not start when it sits out in this hot...its like its got some vapour lock thing goin on...yesterday i tried to start it about 10 times throughout the day, it turned over but wouldnt catch or even chug...so i pulled a plug to test the spark and the first time i cranked it to test, a poof of vapour came out of the cylinder and it fired up on 3 cylinders no sweat... today its same as yesterday, not wanting to start...it starts, and then stops right away...if i give it gas when i start it it chugs a lil and then starts, but i gotta hold it at about 1500rpm for about 30 secs for it to stay alive and then its fine.... when the motor is cold, its got the irratic idle like ive got a vacuum leak, sometimes...once its warm, its fine when its cold i will start it, it should idle about 1200rpm right away, right...well, itll start, drop to 750rpm, then after about 30secs jump up to 1200rpm where it should be when its cold...and chug a lil

hopefully we get some response since there's two of us...on the hybrid forum someone told me it may be because my plugs arent in tight enough...im gonna try that tomorra, but we'll see...id still like to know about how to route the vacuum lines...
