We have a 1999 dohc,5 speed,sedan with 265k we had a mishap with a power probe and in need to reprogram our CPU.Any suggestions?

 

Welcome. What EXACTLY did you do? Does a scan tool communicate with it?

 

a friend has a scanner that can communicate with the pcu. But fail to have engine control commands to turn on. But can open trunk turn on and off evap solinoid. But not iac, tps,fuel injector,or dis coil.we are currently checking all grounds,next is the bum…thanks for replying

 

What happened with the power probe?
If were were back probing when this happened you may have blown the driver (transistor) that provides the reference voltage. You can fix these by replacing the blown transistor.
