Hey, my friend and i have completed a b18a1 into his crx DX, but we are having a bit of trouble with the wiring, so having no idea what were doing, we go ahead and try to start the car.. it is turning over fine and kicks a bit, but wont start.. then we finally got it to start, but it wont rev over 2 grand or else it bogs and dies. We even got the car to run fine, but we turned it off and couldnt start it again... Can anyone help us who has had a similar experience, or possibly tell us what sort of things we should be rechecking? we are running a PR4 ECU

i dont know how to use windows movie maker, so i ended up combining two videos. the 1st part is when the motor was trying to start, the 2nd part is the motor idling, no exhaust btw.

thanks.

 

ok heres whats up, we hooked up a PM6 ECU, seems to run fine now, but heres our problem.. when the block is cold, it starts up and runs fine, but as soon as the engine warms up. it stalls, and when we try to start it, it spits and sputters and sounds like its not on all 4 cylinders.. when we come back the next day and try it, starts up perfect.. then once again when it warms up.. stalls.. does anyone know what the problem could be? thanks

 

did yal convert it from dual-port fuel injection to multi-port?

 

check the dizzy my car did the same thing but it wouldnt rev over 5k it would sputter and **** then wouldnt start up when warmed up had to let it cool then ran ok except for not revving over 5k replaced dizzy ran like a champ

 

yea man, its prob something with the spark because not that long ago, some guy in the civic 92-00 forum had the same prob where he did a swap and would take a while for him to turn it on, and when he did, he wasnt able to pass 3k RPM's...it was like if he had a rev limiter set at 3k...what he did was tryed new spark plugs and new wires and problem was solved...

 

It sounds like ignition coil, check that or replace the distributor like the last guy said!!

 

map and tps plugs swaped? Sounds like it.

 

none of yal are realizing that the that the 88-91 civic dx's(d15b2) had dual port fuel injection(2 injectors) and in order to get a multiport fuel injected(4 injectors) engine such as the b18a1 to work....you need to wire up the other injectors to the ecu.

since the OP stated that they had no clue how to do the wiring....then i would say that would be were to start.

aaah...i never really work on crx's (obd0) and i def didnt know about the dual port fuel injection...good to know and does seem to be the case like you said about him not knowing how to wire it...now,my question to you PROJECTTEG is, are all obd0 civics/crx like this??
