hey, my civic has the stock D15b1 and i know the ECU is thowing codes because the check engine light comes on. the problem is that after the first time i start it and shut it off, the car wont start. i just had the battery charged to day at auto zone, it was reading 12.41 volts on the volt meter (which is where it should be). My mom drove my home in the suburban, just so happened she needed a battery too. This happend before i got the battery charged also. i need to know where the ECU is so i can check it for codes. now, im familiar more with odbII systems because i've had some training with scanner tools and stuff, but i know you cant use a scanner on a obd0 car like mine. when i find the ECU, am i supposed to turn the key to the on position (without starting it) to have the obd0 ecu flash its lights for the codes? i'm pretty sure i know how to identify the codes, long flashes rep. digits in the tens' spot, like 2 long flashes back to back would be 20, and short flashes work as single digits? sound right? i'll be sure to post the codes being thrown when i found out where the ECU is. oh, yeah, and i am pressing the clutchin all the way, and it does the same thing in either of the four gears and reverse, not that it matters cause the clutch is in, separating the engine from the tranny. and the car is in need of an oil change, if thats in any way relevant.
