i went thru the fuses again, this time with a magnifing glass, and i could'nt see it with the naked eye but i could see it was bad with the magnifing glass. it was one of the 20 amp fuses.

If you car is running then it's just hooked up wrong. Power to an ignition wire(can use the ignition terminal on the fuse box),
Needs good ground, White wire to ADL
If you check engine light comes on when you turn your key to the accessory position and you have no reading on your Scan master then it's hooked up incorrectly
