COMPUTER DIAGNOSTIC CONNECTOR ALDL

The Obd2 Scanner Is Getting A Error Message Saying Not Reading The Vehicle. What Could Some Of The Problems Be? First I Had Two Codes...

Plugged In A Brand-new Scanner Which Wouldn't Communicate And The Truck Won't Start And Electrics Acting Funny.

Could You Please Tell Me The Location Of The Obdii Connector On A '96 Ranger P.U. Thank You

I Have A 1995-96 Mercury Mystique, Check Engine Light Is On, Found Plug For Scan, But It Won't Work, Is There Another Way To Test?

I Just Picked Up A 1995 Mazda 626 Cronos, 4 Door, 4 Cylinder, 2 Litre Engine, Automatic. Great Little Car. It Has A Little Problem...

Connector Is New (replaced), But Still Will Not Communicate And I Cannot Get Emission Test.

I Can't Find Which Fuse It's Paired With. Thanks For Any Help.
