Truck wont start but i still have battery power

Put it in Neutral and push the truck to roll and keep key in On position and then engage gear to drive.

You should actually repair the vehicle instead of creating a dangerous scenario.... If you have power to your vehicle and your lights are coming on then that's good. Your battery is fine. Depending on if you turn the ignition key and hear the vehicle try to turn over or not is key to discipher what is going on.... Or isn't going on
