Hello, I'm new to the forum. I've found these forums the most helpful when it comes to mysterious car

So with that being said, here's my dilemma I bought a OBD 1 and 2 diagnostic tool to test my 1996 Mazda 626. Waiting for the week to get this thing, plug it in and nothing. I'm hoping it's a fuse for the diagnostics, but I have no idea which fuse it could be if that's the problem at
anybody have any idea? Any help would be greatly appreciated

 

Find a parts store that does diagnostic code checks, get them to try your car, this will tell you if its a fault with your car or poor quality test tool purchased.
