I have a 2002, 4 burner Hyundai Santa Fe. I was driving my Santa Fe for about 50 miles when all of a sudden it started acting weird. The RPM's went between 3,500-1,000, it felt like I was hitting turbulence, and then it died. My first thought was the fuel filter, so I replaced that. It ran for about 10 miles, and started acting up again. My next thought was the fuel pump, so I replaced that, and that didn't solve the problem. When I turn the key to on, I notice that the pump turns on, but I unhooked the cables to see if it was actually pumping fuel, and it wasn't. I then turned the key over, without pushing the clutch in to see what happened. It started pumping fuel at that point. I have found that if I turn the key over before trying and actually turning the car on, when I do go to start it, it will start and run for about two minutes, before it starts to act up. I cannot get it to stay on long enough to drive it even mile. It has about 130,000 miles on it. I hooked up a diagnostic reader, and it threw four codes.
1. Camshaft positioning sensor
2. Crankshaft positioning sensor
3. MAF or VAF low input
4. MAF or VAF low input
I need help with this problem, and my dad mentioned that I put the problems up on a forum. If you have any idea what it might be, I am open to all suggestions.
