Out of the blue the other day, our 2007 Elantra started dying horribly at around 27-2800 rpms. It has absolutely no power, and the engine lugs like it just doesn't want to fire on all cylinders. If you cruise at lower rpms, it shifts fine, so we're pretty sure it's a problem with the fuel somewhere (its also throwing a code, but we don't have a diagnostics computer handy to get it).

I don't have a Chilton's for this car so I'm completely in the dark on a few things. Afaik, the fuel filter now resides inside the pump on these models; can it still be replaced seperately from replacing the whole pump? Napa doesn't list a part for just the filter, they can only find the pump, and I think this would be a pretty nasty move on the auto-makers behalf if I can't change my filters anymore without replacing the whole assembly...

Plugs are new, wires are fine, fluids have all been flushed and replaced recently, along with the air and oil filter, so it's not a basic tuneup issue at this point, so far as we can tell. Anybody ran into this? The car only has 30k miles on it.

You need to scan for the trouble code before you assume anything.

There was a fuel pump recall on certain Elantras over a year ago. You can read more about it on this thread: http://www.hyundai-forums.com/index.php?showtopic=28770.

"You need to scan for the trouble code before you assume anything. "

Appreciated, and I would be happy to drop $200 on a new handheld diagnostic computer, but we're out in the middle of the desert. We're going to spin by Napa later and see if they'll let us use theirs, but it's a little troublesome driving a busted car 2 hours into Vegas to get the code run.

I checked out the bulletin on the fuel pump recall, looks like it doesn't cover ours. It's for 2008 (cars built after nov 5th, 2007) and ours is a 2007. We'll call Hyundai to double check, who knows.

The computer and sensors that typically affect driveability and would throw a computer code are all emissions related so should be covered under the standard warranty. Why not let Hyundai do the work?

Because as I mentioned, it's a little hard to drive a busted car 2 hours+ into town, when it has trouble getting above 40mph.

My apologies if in that last post I seemed a little frustrated. It's just that I know getting the code is important, but living out in the middle of nowhere, it's not as easy to just take your car in, and a lot of work, covered by warranty or not, is a million times easier to do yourself.

We had a friend come over and hook it up though, it's throwing p0335, crankshaft position sensor malfunctioning. So now I'd like to locate and replace that if I can. Going to have to wait until it's light out though. (IMG:style_emoticons/default/smile.gif)

Has anyone ever used the Hyundai roadside assistance that comes with the warranty? I wonder what would happen if you drove a few miles from home, then called them and asked to have it towed to the nearest dealer.
