Hi there. Just wondering if anyone could give me some guidance. Have recently bought a second hand 97 Sonata V6 with roughly 140000kms. The car drove great for a week but now I'm having an issue. The car lost power and stalled while I was highway driving and cranked but didn't want to start. I have replaced the ignition coil but that didn't fix the problem, I then thought it was the fuel pump but have run a couple of tests and that seems fine too. Would replacing an alternator help or could it be not getting enough voltage from somewhere else?
