My truck slowly started getting worse. first, the dinging noise that your car makes qhen the keys are left in the ignition or if you leave your lights on, my truck would make this sound with no light on or key in ignition causing the battery to drain. then the gauges started acting crazy, completely not working at times. now my truck will not start, it turns over but something doesn't catch or fire. i have replaced the battery numerous times and the spark plugs are new.
