99 jmmy current draw

In my 99 jimmy it has 12 volts of draw. I did a few test to see if it dropped, took each fuse out, took power off alternator,removed keyless/remote start,removed radio. Tryin to find what is causing the draw. It wont start after sitting for like two minutes anymore, gradually has gotten worse as it has been geting colder. Took the + off the batery, placed the - lead from DMM (meter) on positive, then took + lead from DMM and put on positve power wire that goes to car. Read -12.10, i played around on the starter trying to see if i took off its ground if it would go away, it di not. so i took starter out, still nothing. put back in and decided that i would run continuity test it was far from open, was boucing all over. Then i tried to test and see if it was grounding out between batery and starter, it was the same reading on meter at + of starter as it was at battery wire by the battery. Any ideas of what could be next. The battey under no load is at 12.00...or close to above. As soon as i put the power to the battery it drops by litterally like -.5 volts off the get. When i cranked early in the day it dropped to 5.6 and obiously didn't start the car..,..i hate not knowing what is going on, but it seem like there is something going on in the starter mech. Could the starter have short making it do this? or is an electrical Gremlin that i need to tack down??? thanks, mike
