found the problem , appers to be a engineering problem at gm , there is a plastic rod that comes out of the soleniod and out to the area where the lock rod (that goes up the key tumbeler) goes on , at this area there is a rubber cup that fits into what looks like a plastic cam , the rubber deteriorates causeing the plastic rod (fromt he soleniod) to come out of its joint so the rod that comeout of the soleida just flops about when you press the button , i guess mine was going in and out of socket like the hips of a woman pregant for quints
ill post pics later
