disconnect all grounds physically and chemically clean before reconnecting.

Make sure your Electronic Brake Control Module isn't bad. Mine went out on my 01 3/4 ton burb. http://www.modulemaster.com/en/Chevy/Chevytruck_info.php will take care of you on that part with better than OEM and wayyy cheaper. Can't remember how I diagnosed that but it was simple to fix.

The ABS sensor issue is also ground related per the TSB on that. There is a body ground strap on the driver's side just behind the driver's side front tire if I recall correctly, and you have to clean the mounting surface of all corrosion (resistance) before remounting thhe ABS sensors.

Good luck!
