Do you have the code #s? The problem might be that someone who is working on your car thinks that the code tells you which part to replace---it's not that simple. The codes only indicate the system or circuit that is in distress. They may be replacing the symptom but not installing the cure, in other words.

Thank you so much for answering me, Yes the code seems to be p0301 and I only know that cuz a friend of mine has the machine to read it and it says a misfire in cylinder 1. the car drives great, its the starting I have a problem with and now, seems to idle rough a bit since hyundai has worked on it. They say they have no clue, since they have checked everything(so they say). Now they say it might be electrical and thats big bucks!!!! I just dont understand it, they put in an air idles control, fuel pump and #2&5 injectors and now a coil in #1. and tell me that this is what the codes are reading?????Please any help is greatly aprreciated!!!!

Mike, (or anyone else)
Have you continued to have this problem?
We took the first bad fuel pump to a shop. The second time (a year a week after) I refused to pay $650 again. I ebayed a used part ($60) and picked up the Haynes manual. I found it's pretty easy to change out (there's a hatch in the trunk and it slides out nicely). I popped open the housing and found my wire all burnt up too.
This morning the fuel pump failed on the way home. I'm almost certain I'm going to find that same wire toasted again. The tow truck guy (who also runs a shop) recommended swapping the fuel pump fuse with a lower one and never letting the fuel get too low (come to think of it I happened to be low on fuel each time) because the fuel keeps the pump cool.
That and the airbag lights (which I'll have to try your solution) are the only issues I've had as well.
The fuel pump is getting ridiculous, especially since it seems like there is no one else online with the same problem.
#3110 of 3236 Crankshaft postion sensor

I have a 2001 Hyudai sonata 4 cyl 2.4L engine with 126,000 miles on it. I tried to start it and nothing happened, I've just replaced the altenator and battery. I moved the gear shift in and out of Park thinking that the transmission was not in park all the way and still nothing, tried jump the car battery and still nothing, did the same thing with the transmission during this process. After about 5 min the car started but then the check engine light came on, had it checked out and the code was P0335, Crankshaft position sensor. Outside the where there code was checked the car did the same thing it just didn't take that long, it started up after one turn off of the ignition. Would that sensor cause my car not to start or could there be another issue?

Sep 06, 2010 (3:59 pm)
I've a 2009 Sonata V6, 11,000 km. In Drive, when revs drop to 1200 or so, light gas pedal pressure causes car to miss, cough, snort. Increasing revs to 1500 or 1600 ends problem. The car is always in 5th when problem happens. If I shift down to 4th, manually or by applying gas firmly (not always possible when you're in traffic), revs increase of course, and problem disappears. Has anyone else had this problem? Know its cause? Know what to do about it? I've had car into dealer 4 times with no success.

If this is happening around 40 mph you might want to do a search on previous torque converter postings.

I have a 2003 Sonota that had a similar starting problem... turns out it was the alarm system disabling the ignition. The cheapest solution was to have a remote starter installed and that cured the problem. Now, of course, my electric door locks will lock by themselves so I can't leave my keys in the car anymore.

The crankshaft sensor monitors the relationship between valves and pistons in the engine to maintain the variable valve timing. It is also measures the engine's speed by calculating revolutions per minute. The crankshaft sensor is in effect a catcher in a baseball game, calling the game so the pitcher (the engine) can fire the appropriate function, or pitch,
Symptoms of Problems
When a crankshaft sensor has failed or is failing, certain timing problems will arise in engine function. The engine may start normally in some cases, but will cut off after a few minutes (or seconds) of operation. More than likely the engine will be unable to start at all. Since the crankshaft sensor is responsible for engine timing, the driver may experience engine backfire or irregular rpm function, if the vehicle starts at all.
