I don't know much about cars but I'm trying to learn about my car and local the initial problem. I've got a 2000 Hyundai elantra. After getting gas I have problems starting, it turns over but takes a bit to start. Then out of the blue my car wouldn't start. It kept blowing the ignition fuse. My boyfriend replaced the started. He said it tested bad. So it ran for a whole day then quit turning over. The stereo and stuff turns on but it won't turn over even with the new starter. My bf switched around the little black relay things in the fuse box and it was turning over wouldn't start. Which I assume is due to not having all the other fuses in currently. We should have it running later today, but I'm just wondering what could cause that little black relay thing to blow or mess up. Any help would be appreciated!
