I vaguely remember my dad having this problem with his 90 chevy truck. I know it sounds stupid and remedial but he would just disconnect the battery for a little bit. 30 minutes maybe? I remember this because he had a disconnect switch installed on the battery for that reason. Worth a shot if you haven't tried it already.
