When I start my truck I can't turn it off with the key in the ignition. I can only shut it down by pulling the ignition/ecu fuse. I replaced the ignition switch with a new one and I am still having the same problem. I put the new switch in, adjusted it forward and backward to find the start and stop positions, but I can't find the stop position. So I took the switch off the column and with a screw driver I went through all the positions and I can make it start, but not stop. What am I missing? Please help. Thank you.
