99LSGUN

hey guys, i recently took my car out of storage and i had to put a new battery in it.... everything was working great and then one day i tried to start it up and it hesitated for a sec like the battery was dieing then evetually it kicked over. the battery was about 3 weeks old when this happened so i dont think it could be the battery i had the alternator checked it is working perfect. and then the other day i was messing with it and i tried to start it and it hesitated and all these lights came on..... ABS INOP, AIR BAG, SERVICE VEHICLE, THE TRUCK EVEN POPPED OPEN. i got no clue what this could be is it a short?, is the battery not grounded correctly and it is draining the battery? i need help please thanks guys.
