My blazer has a check engine light that is on and the codes that have come up are p0740, p0785, p0753, p0758 and p1860. The key will not turn back to the off position as well. I have looked at the ignition for any signs of shorted wires etc. All I realy noticed that the acutator has a little crack in the plastic and the button does not seem like its spring loaded. Every once and a great while the transmision will work ok and the key will come out on its own. The transmission fluid level is correct and looks to be ok.
