Alright. Its beeb awhile since ive got on. But ive been havin a problem with the truck. I threw a new optima yellow top in. put a new key cylinder and ignition switch in the column. And I still have a security light. Relearn process for the key is suppose to be easy I dont have an alarm system factory or installed. Now if u know about this. It puts the truck in a fuel lock out mode prevents it from starting.untill that security light is out it will not start. Ive done a relearn process multiple times. Have got nowhere. Any suggestions??? Thanks
