RepairPal Certified shops can diagnose and repair your 2004 Nissan Altima. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
You probably didn't flood it. That rarely happens with newer cars. I'd have this inspected at a shop before trying to start it. Use this link to find a good shop near you.
