Re: 95 2.2 driveability problem
So why wouldn't it connect to a scanner? That is the question. That usually means a 12 volt supply to the computer is missing. There sould be one constant battery voltage and as many as 4 keyed power. And don't forget the ground circuits. It is possible to have one keyed supply missing and still operate but a few items may not communicate. It might not set a code because the system doesn't know it's supposed to be working. Get a diagram of the ecm connectors and trace it to see what is missing. A long shot is a faulty output to the ALDL. that usually translates to a defect inside the ecm. Check the wiring first.
