I have a 00 civic si that I recently dropped the #3 cylinder in... bought a B16A Gen II (OBD I) to put in... p28 ecu, converted and chipped, and obd IIb - obd I conversion harness. Now when i try to crank it tries to run for a second or two then dies. Checked timing 3 times it's fine fuel seems normal no CEL? Any suggestions???

 

check the spark plug wires y0 to see if they're in the correct positions

 

I have a similar problem. Although mine may involve more than yours. I'm trying to run the P2T, stock 00 Si ECU, on 310 cc injectors. I'm changing the spark plugs soon to see if they are making the problem. Passing emissions in GA is a bitch.

 

try checking the IAC...i did the same swap into a 98 civic and mine dies after a few seconds of running...

 

lol get this... the car was up on jack stands and the gas in the tank wasn't enough to start the car! i'm such a dumbass sometimes. hey blaze the chemi... pleeze don't tell me ur running that ecu on a gen II b16.. u know those are obd I right?? The ecu is obdII. it'll run, but like crap and u can forget passing emissions, glad I live next door in bama, don't have to worry bout it.
