    You could try disconnecting the battery for 20 min to reset the computer...

    But you may have fried something trying to jump the truck, if done improperly.

    Hkey? Afaik, the PTS turns off after 15mins. If it's PTS, you may have jumped it backwards.

    You might just need a new battery. These cars now have so much sensors and electronics they need battery voltage to run properly. So a bad battery or low voltage can cause it. Even air bag lights can stay on with low voltage battery.
