So I just bought this 97 grand prix se today. 3.8 V6 in it. Needs new brakes, rear struts, tires, and a blower motor (had my mechanic check it out before I bought it). Go out tonight, mechanic is gonna do all the fixin's tomorrow. Went to leave my buddy's house, and start the car before I leave. Starts just fine. Go back in, grab the kids load them up in the car and go. Get about half a block down, and the car starts to die. Check engine light comes on, and the car just DIES half a block away from my buddy's house. I call him, he checks it out with my boyfriend, and they think it's the alternator. Try to start the car again, and it TRIES to turn over, it just won't start. Full tank of gas, and the battery cables look solid. HELP!!!!! WHAT IS WRONG WITH MY CAR???????
