so does anyone know why it wont connect to the test machine? Is there a fuse or a line I should be checking?
the emmisions tested but they pluged it in and said that it had no connection. on 1998 GMC Savana 1500
check for power at the diagnostic connector
I agree with gg. I think it is pin16 on the dlc, bottom right should have battery voltage.
