Welcome to AF.

Were you getting power to the Actron scanner and did it respond by giving no codes?

I am sapose to be getting power from the plug under dash.and it does nothing the screen is blank

Yes, the scanner should use power off the data link port. I'd test the scanner on another odb-ii car first if you have not already done that. I recall 12 volts to the data link port feeding off the fuse for the cigarette lighter so check to make sure it is not blown.

You're welcome.

Thats sorta good news. Which engine do you have? P0102 means the PCM module has detected the MAF sensor is not generating the right frequency and will need replacement.

Thats what I came up with It's a 3.8 thanks again
