Chevrolet Tahoe 2005 5.3/ 4x4 380000 miles
So I changed out my pcm with another, tried resetting it. Failed! Swapped ignition switch that matches the pcm swap. Still nothing. Now my battery dies within minutes of attempting to try anything. Any help will be great. I must add if I put my original parts back on it cranks!
