i have a 98 civic stock 1.6 non vtech that i am having an issue where i cant get my scanner to connect to the ecu. ive checked all the wiring and fuses and nothing is bad or disconnected from what i can tell. when i put my power probe on the ecu fuse its showing ground, is this normal, and if i put power to it, it will start the car without the clutch in or anything. could this be an internal fault with the ecu or am i missing a ground somewhere? i did recently put a clutch in the car so if you know of ground that im missing where is it?

all help is appreciated

 

What ecu are you running?
Why do you need to connect to a scanner?
Why don't you jump the service connector to see what codes flash?

I dont know what ecu it has. The cel is on and need scanner ability for emissions testing. Thank you for the plug thing though I didnt know that. I can get the ecu info later

 

recently i located a break in my ecu wires reconnected and now the cel light is off but will not come back with still no connectivity at the obd2 port

 

post the part # on the ecu.
