Sounds like an auto parts guy told you that. Try another key if you have one not a new one. The diode may have mismatched and not allowing to start. Then if it starts you can reprogram the new one to the truck. If security light is on or flashing when trying to start even with other key it will need to be checked by mechanic with scanner. Also you can try what is in pic to see if that will make it start. Finally if none of this works scan for codes as it may be a bad crank or cam sensor
