Okay...I have a 92 civic si and just swapped a 95 b18c1 into her.... Took for a test drive and ran fine all the way up to 8200 redline... after about 10 min of testing, she cut off. Got her back to the house, and then she would start, then die right away.

Replaced distributor and swapped fuel pumps from a 95 teg (think they're the same, so shouldn't really matter unless the fuel pump was bad, but has been swapped), she started up, idled about 5 min, then cut off. Swapped ecu's from a 93 teg, same deal. Starts and cuts off immediately.

Checked spark from plugs, getting spark. Only error codes from ecu are 23 (knock sensor) and 41 (o2 sensor), neither of which are hooked up, but shouldn't effect my car actually STARTING and running...

Has new tank of 93 octane gas, so not worried about gas.

If you need any other info, please let me know....other than that....any suggestions? I just want this girl RUNNING!!! Any help would be appreciated.

Ok, you have spark, have you checked for fuel? do a compression check as well.

Try grabbing some carb cleaner and spray just a little and try starting it. That will tell you whether you have a fuel prob or not.

totally different beast but, i had map sensor that went on me in one a my civics, it would run until the car warmed up then die, once the car cooled awhile it would run again for a few minutes at a time, if you got extras kicking around try changing out the sensor for the hell of it. but what the hell do i know bro,lol
