So my check engine light came on...but my obd II port doesn't work.

What the heck do I do? I've been told it could be the ECU. Anyone have a stock one laying around I can borrow to see what code I'm throwing. These problems are getting old

I would focus on fixing the OBD II port. Assuming you've tried more than one known good OBD scanner, it seems most likely that the problem is at the OBD connector in the cockpit. Scan the CEL code once you get the port working, and go from there.

I've tested the port for voltage and all and it seems to be fine. Do you know any specific tests I can do?

Also, the previous owner had some issues with the port as well, and sort of told me it's more than likely the ECU. I'm not sure though. Would a bad ECU cause the OBD not to read?

I know this doesn't directly help but I had to take mine to 4 different car parts stores to find one that their reader would work on my car.

Autozone won the day, but just write down the codes because their readers explanation of the codes were wrong

Same experience here.... Also, the guy at Oreillys told me that if I bought a reader from them and it did not work on my car it could not be returned. However, buy one from Sears and you can return it for any reason. I bought an inexpensive one at Sears and it has worked great.
