I have a 2003 chevy venture...yesterday I went to start it and it acted like the battery was dead, but it still started. Then today, it wouldn't start at all. So I jumped it and it started. Took it to the store, and it wouldn't start again. So once again had to jump it. I brought it home and let it run for like 30 minutes. I went back out there and on the little screen it was saying security...turned it off and it wouldn't start again. But this time there was no clicking or anything. What could this be??? Please help, I cant afford to take it to the shop.
