I have a 2004 Hyundai Santa few 2.7l v6. I've been having problems with this car for a while now. I've already put some money into it, I got the fuel pump, fuel pump relay, the alternator, ecm, and purge valve fixed. I just recently fixed the ecm it ran great right after we installed a used part we purchased. Today it started up great we drove maybe for 45 mins, stopped to get food (40 minutes at a restaurant) on our way out the car started and we drove out of the parking lot then we stopped at a red light right beside the restaurant and the car just died, we tried to crank it back up but once again it wouldn't turn over. I don't know what else I can do or fix. Please help!!!!!
