I have a 2008 Accent that just died while driving the other day. When we plugged in the scan tool it told us the cam positioning sensor was bad. So, we replaced it. After that it still will not start up. I'm thinking that there is an issue with the fuel pump. I flipped the seat up, took the cover off the expose the tank so I could listen. When I turn the key to the on position the pump only buzzes for a few seconds and it doesn't kick on every time. So, i disconnected the line from the rail and fuel isn't pushed out until cranking the engine. seeing as fuel sprays out I'm not sure if this is normal. Am i right to think the fuel pump is shot? or is it an issue that could have been caused by a bad CPS?
