I drive a swapped ek coupe with an lsvtec. Car died at import alliance and wouldn't get spark. Changed the coil and it started. I drove it 20 minutes and everything dimmed out. No tach, radio, nothing. tested battery and alternator came back bad and replaced both. Everythkng started good and this morning it died again and lost all power. I have no idea what's going on. Can anybody help?
