2004 Sonata stalls out for no reason then won't start

My 2004 Sonata stalled out the other day for no reason. The other day I was driving up a hill and the car seemed like it has a fuel injection program and was jerking. The check engine light flashed a few times then the call stalled out. I restarted it and went a little further and it stalled out again this time it woudn't start when I tried to restart the car. I waited a few minutes and then the car started. I drove a little more and it did again. I finally parked the car and had it towed. Now the Hyundai dealership is telling me that they can't find the problem. My car has 94,000 miles on it and current service records. This has never happened before.

    My car just shut down while driving on a busy street with no warning. It would not start back. Had to have it towed to the dealership. At the dealership the car started again. They had just done the 60,000 mile maintenance 3 days prior to my troubles. The dealership could not find a problem. Had it about a day when the same thing happened while backing out of the driveway. After a while the car started up but the check engine light came on and stayed on. I have not driven it anywhere else because I am afraid to.

    I just put gas into to my 2004 Hyundai Sonata and when I went to start it, it wouldnt start so i pressed on the gas really quickly and and it was okay ad it has been driving okay every since. This is the second time this has happened.

    I have the same problem. The mechanic said, I need to get the fuel injection cleaning done once and said, everything will be okay. I haven't got this done, instead want to check thats the exact cause of the problem.



    Thanks,

Hi there, i have a 2003 sonata and my car did the same. it stalled and the engine light stayed on but managed to get going again. i took it to Hyundai and it was the crank angle sensor. it needed replacing at NZD180.00 with 3 hours labour to do it. evidently they remove the front of the engine and cam belt etc. the workshop at Hyundai did it and charged 3 hours, not sure if that was excessive or not.

My 2004 Sonata is doing the same thing. The engine light comes on and then the engine just dies. My mechanic put it on the diagnostic machine and can't find anything wrong with it. So did the crank angle sensor fix the problem on your car scottyinauss? I am going to print out your input and take it to my mechanic. Thanks.

Repaired ---what?

I don't think so

How about the EGR Valve or Ignition
Misfires?

What about check lights on the dash & codes?

TPS Sensors

SOURCE: hyundai sonata 01 jerking slow take off high idling

P0715 = Input Shaft Speed Sensor Malfunction
P0765 = P0765 Overdrive solenoid valve problem
The Input shaft speed sensor is located on top of the trans (center) under the shifter cable (the shifter cable is connected to the transaxel range switch). The Overdrive Solenoid valve is located INSIDE the trans (oil pan must be removed to access it).Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

SOURCE: my hyundai sonata 1998 gle is idling rough and

it might be time for a tune up. check your sparking plugs and replace with either ngk or nd. also check your coil pack boots for "tracking" which are little white lines indicating electrical arcing towards ground. if there are signs, replace them. this sound like a simple repair given the information you have given me. this should work. cheers.

Jeep starts once it warms up it will die out but will start up again it might take all day before it does again


the 4.0L I-6 inline 6, over 5 million made. (owned 3 for 500k miles)
it can only be 3 things, bad engine,bad spark, bad fueling.
(and others, EGR stuck etc)
but you never stated the GOOD,just bad.
does IT Have full power up hills , if it does start.? hot or cold power?
a key fact,
and key fact 2? can you save the stall, with a fast right foot.?????
stalls 101:
  1. never ever tuned up in decade. (most owners !)
  2. stalls for bad spark ,see #1
  3. stalls for lack of fuel, see #1 and new fuel filter.
  4. EGR stuck open engine will stall. (some 4Ll have no EGR)
  5. Lost fueling,
  6. Flooding

there are simple tests to find it, my guessing is fruitless waste.

ALL day no starts.
cranks robustly does it (guess yes)
(lost spark, test for lost spark x6 (and at coil)
lost fueling, Spark trips dry test.
flooding, spark tips dripping in raw fuel, test.

so ever get a tune up,or just driving it till it drops dead, like most do.

While i am driving my car shut off itself


you mean the engine stalled.
the cars computer does all it can to sustain running
when it can not for 100 reasons, it stalls.
it stalls for this list of macro reason. (no order)
1: EGR stuck open
2: poor engine compression
3: bad spark or timed wrong.
4: bad fueling. too rich or too lean,. can stall any engine.
even actual bad gasoline. can happen.
5: loss of idle air supply.
except clean EGR /ISC each path requires tests and tools.
got tools, got money for tools, go the time? then get to a shop.

Stalls at low speed when in cruise control


You sould have recieved a "recall" notice in the mail about the cruise control for fire and failure issues. they are adding a fusable link where the cruise control harness connects to the brake master cylinder. if you have not had the recall performed yet you should SERIOUSLY consider getting it done, mainly so it doesnt catch fire, but "could" be the result of the failure you've been experiancing! btw, almost ALL Ford vehicles have been affected with the cruise control recall. hope this helps!

Stalled and will not start


I would replace your fuel filter. It is cheap and should be easy to replace if I was going to guess. A clogged fuel filter will cause poor fuel flow and can cause stalling. If that doesn't help I would get to a repair shop because cars are difficult to diagnose without a computer nowadays
