Hello All,
My name is Corey and I am a bit new to these Forums so bear with me. I know there are threads after threads in this Forum regarding Engine misfires, etc. cause I have read MANY of them after my recent experience. So if you will, please hear out my situation, as I feel it is a bit of a unique one and would love to get as much input as possible.
So, It all began about 2 weeks ago. On my way home from work, on the freeway, I stepped on the gas (about 90%) and boom, BIG hesitation and a couple sounds that I could only describe as an engine backfire. Along with that, my Check Engine Light flashed for about 10 sec. and then disappeared. Not thinking much of it, I shook it off as a weird fluke.
Then, a couple days later, my wife used the car to take my daughter to school. She brought it back to me with a fully illuminating check engine light and she explained that the car felt very weird (More hesitation, and backfires). I have since forgiven her
. That night, I took my car over to the nearest Auto Parts store to use their OBD tool. Plugged it into my car, and viola, Misfire in Cylinder 4. Devastated, because I love my little VT, I took it to the Dealer the very next morning (FYI, I'm at 68,000 miles and was very worried about what would be hitting my wallet).
So, above is my Service Log. After having my car all day, they called me and told me that they feel like it may be my fuel pump. BUT, they insisted that I get a new battery, because as you can see by the battery test results on the right, my battery was measuring at 284CCA instead of the 550. They said, once I get a new battery they would test the fuel pump again to see if fixed the problem. Again, as you can see in the Service notes, my Fuel Pump was putting out 579 PSI at 1600 RPMs instead of the required 1000+ PSI.
So they explained, if they replaced the battery, retested the fuel pump and it still was shorting the PSIs then it was a bad fuel pump. And of course, low and behold, at 68,000 miles, that is not covered under the 100,000 mile Powertrain warranty, resulting in a Service bill of near $1,000 on a car that I still consider New!! Anyway, I said no way, I cant believe that, so I picked up my car. They cleared the CEL and has yet to come back on since driving it. It still drives completely fine, but, I do "test" it from time to time and sure enough, as soon as a little extra pressure is applied to the gas pedal, hesitation occurs, but no CEL as of yet. So here I am, pleading to the Forum Geniuses that know a whole lot more about our Vehicles than I do.
I guess, all this comes down to a few questions.
1. What would you do in my situation?
2. Can a weak battery REALLY cause my Fuel Pump to come up short on PSIs? And if so, do you believe a new battery could fix this problem?
3. Do you think it is worth Calling Hyundai about this, see if they could pull some strings and get this covered under warranty?
Please, if its not too much to ask, any help or guidance would be GREATLY appreciated!!
Thank you to those that read through my sob story
