i have a b18a1 in a 93 integra. was running for a while on idle then went to change computer chips and the would not start back up. after that i put original chip in a still no start. i have changed distributors and nothing still no spark if you can help me it would be apreciated

 

Did you pull the power for the ECU before taking the chip out? Try taking the negative terminal off for a few mins then re attach.

 

more detail .... what exactly was you doing ?

 

yea sounds like u messed up the ECU, double check everything u did, fried something it sounds like

 

i know the ecu works because i have tried both chips in my car perhapse maybe i blew a fuse or relay that controls power ? but i know its not the ecu thanks guy for comments any other advice would be helpful as well

 

r u 100% have you tried it on another car to test?

 

Under the hood, passenger side, close to the fire wall there is a fuse box, Check the 7.5amp and 10amp fuses, those are for the ECU.
