truck ran fine started no issue then would not engage the starter solenoid. Jumper the solenoid and would start and run. changed out the ignition switch (not the key tumbler set) , still no power to the solenoid and now will not start when jumper. pulled solenoid and it seems to be working. Checked the plastic rod it is moving even pulled the switch back off and tried to manually slide the pin to start and nothing. Pulled the key assembly and the end is not broken and seems to be working. I even pulled and check every fuse and found nothing. Is there a relay that might have failed? Natural switch?
