working on a 97 prelude, just swapped a h22a in it and now it wont get spark. however if i put any other ecu thats not from a prelude into it it will start but run like crap. so far we have replaced the coil dizzy and the crank sensor and ecus. and swapped out harnesses. this is really aggervating and any help would be appreaciated

 

Are you getting a green flashing key on your instrument cluster?

 

no he is not, also have tried 2 stock ecus.. it starts right up on a d16y8 ecu for some reason though or basically any ecu other than an stock automatic one that should be in it...

 

do these ecu's ever need reprogrammed? i have never had to reprogram them in previous swaps on bb6's but im stumped

 

how many miles??

 

on motor n ecu

 

i was thinking maybe an immobilizer issue but if the green key is not flashing then problably not. Is the engine obd1 or obd2. I am assuming that if it is obd1 you did change the oil pump so that you have a crank sensor right? No it shouldn't need reflashing.
