    Hello i hope someone can guide me to the right direction we have an issue with our truck it’s turns on perfectly but once we turn it off it won’t. We removed the fuse that is located on the batteries to turn it off but we have no clue on what’s going on please help us fix this problem thank you in advance.

    turck wont turn off? Does the gauges and lights on dash turn off? Sounds like maybe you need a new igition switch either way. But thats just thinking off top of head. Byt removing the fuse, you are turning off the ecm mounted to the motor. So im gonna stick with faulty ignition switch. They do go bad. Pull the lower dash panel with igniton switch and with truck running, pull one of the hot wires off switch and see if it shuts off
