Hi, I have an 2011 Sonata. It has about 58,000 miles and I take great care of it. Last week my check engine light came on and so did my low fuel light. I had a few other lights pop on and off. I tried to read my engine codes but nothing came up. Next I checked the alternator, good. Checked the battery, bad cell so I replaced it. Still no change in the lights. So I took my car to a mechanic. Bad fuel pressure senor; told the part is $260 and labor is $300. Craziness cause I found the part at Pepboys for $50 and I do a lot of work on my other car and motorcycle so I figure I can probably figure this out with a bit of guidance. Any advice or help would be greatly appreciated.
