Hi you need to charge the battery then test it to see whats wrong. It may just need to be charged driving it for a few minutes in the underground is not going to charge it. If their is any wall outlets down their put a small 10 amp charger on it over night then test it. If you find the battery does not pass a load and hydrometer but their is enough power in it for the Ing. lights, ac panel and the radio to come on but not start the truck and you are going to replace the battery. Turn the Ing. to the On position then turn the Radio and AC controls to off then turn the Ing. back to the off position before you disconnect the battery termials because the AC and Radio could lose the memory and go into default mode. It would mean a trip to the dealer if it goes into default mode.
