Have an 04 Colorado 5 cyl with a mis fire engine light on

What is your question?

I can not get the code. When I plug in my MAC ET50 code reader I get nothing. Just a blank screen. But I tried my code reader on 3 other vehicles and it works just fine. Is the OBD port controlled by a fuse?

What makes this problem better or worse?

running the engine?

Yes there is a fuse to protect the power circuit to the obd port. Check your fuses first. Alex
