code 15 is for the output signal for the ignition. I changed the spark plugs, wires, distributor, rotor, coil, ignition module. and i'm still getting code 15 what's wrong with the spark in my engine? do i need to buy a new ecu ?

 

Do you have a friend with a ECU you could swap for just a test? If so and its not the exact same car make and model dont rev it or drive it. Start it, see if it works and then shut it off. DONT REV OR DRIVE IT!!!!!!

 

I did that and the same thing happend it didnt start. So i guess that means its not my ecu thats bad. it's something else

 

i found out the problem, It was the module in the distributor. The people gave me the SOHC module but i really needed the DOHC module there 2 different modules, so thats what didnt make the engine fire up

 

recently i manage to read of the codes from my 92 honda civic ex. three of these codes i know how to fix, but there are two codes, 30 and 31 (a/t a signal and a/t b signal) that i am clueless about how to fix! any suggestions guys???
