Sonata NF (2006-10) :: 2009 V6 Cranks But Won't Start
Sep 13, 2013
2009 Sonata V6. It was working fine from the last 10 months and all of a sudden, from couple of days it not behaving as usual.
It cranks some times and will start and some times it wont even crank just silent. (However all my dash lights, headlights sterio work fine).
But to my surprise, it started very fine this morning. So not sure, what the problem would be.
My car has 57000Kms and its still in warranty, so, if there is some thing wrong with the alternator, starter motor. will the warranty cover for those parts.

My 2006 Sonata LX cranks and sometimes starts. Usually it doesn't. I checked the spark plugs for a spark, which it has.
I attached a noid light to the fuel injector, and it flashes. I sprayed starter fluid into the throttle and the car starts and stays running.
I ran a computer diagnostic on it and it reads this: ""Monitor camshaft position in the full retard condition or during CWT control. Camshaft switching out of 109 to 141 degrees in full retard position, 70 to 140 degrees CRK during CWT control."
I'm not mechanically inclined, but what to do up to now. Now I'm at a complete loss as to what is wrong or what to do next.

This is my son's car. He said it started losing power and then finally just died on the side of the road. The first thing I thought of was change the fuel filter. changed it yesterday and it still won't start (cranks with no problem). I used my code scanner on it and it showed three codes: P0300 / P0301 / P0305. I really don't think it's spark plugs or plug wires.

I have an 08 2.4L Sonata with 95000mi. When turning the ignition it will crank and sound like its about to start but won't. I was able to get it to start by pushing the gas pedal a bit when it sounds like it wanted to start. Once started, it ran rough and would stall unless I revved it above 1500 RPM. Still sounded like it occasionally miss fired.
I kept it revved until it reached normal operating temp. When I took my foot slowly off the gas, rpm dropped to about 500-600 and it seemed to pulse . I think engine was raising throttle to keep from stalling. It stalls if I try to put in gear without pressing on gas to raise throttle.
The spark plugs were changed at about 70K mikes. I have not read any codes as the car is stuck in the driveway. Could it be a vacuum leak? I know the Entourages have air intake hose leaks that cause rough idle but with a 6 cyl it still runs. Fuel pump problem?

I have a 2006 V6 Sonata that takes its time to get started. It will crank great, but after a few seconds of trying and no starting, I turn the key to the off position and try it again. Most of the time the car will start on the second attempt, but sometimes it requires a third attempt. Here are the facts as I have observed them:
-I cannot hear the fuel pump engage until a split second before the car actually starts.
-There are no RPMs until the fuel pump engages and the car starts.
-The engine runs really rough for a second while the car initially starts and runs.
-When the car is running, it's really smooth. Like, brand new car smooth.
-This issue happens no matter the time of the day or the temperature of the engine.
-The fuse for the fuel pump is fine.
-The fuel pump relay is fine. I know this because I swapped the horn relay with the fuel pump relay and nothing changed with the starting issue and the horn still worked great.
-A friend used a jumper in the fuel pump relay to see if the fuel pump would engage and it did.
-Have not used a fuel pressure gauge as we did not have one on hand.
Is there anything else to check besides using the fuel pressure gauge? Have you run into this same issue? If so, what was the cure? I'm averaging about 20 MPG with mostly city driving. Is that normal for the 2006 V6?
Recent work included new spark plugs, a new gasket somewhere because it was weeping oil there (I think it was the part of the engine that you have to remove in order to get to a couple of the plugs), and the idler pulley thingy and it's belt.
The starting issue started before I got this work done. I took it to a repair shop because of the starting issue and they found these other problems. The funny thing is, they claim that the car started perfectly fine for them every time, which is pretty hard to believe. When I picked the car up from the shop, I tried starting it, it didn't start, but the mechanic was right there to see my issue first hand.
My thinking is that the fuel pump is fine because when it does finally start, the engine runs smooth as silk. I love how when I'm going 80 MPH, just a slight amount of pressure on the gas pedal and I'm up to a hundred in no time flat. I love this Hyundai V6. Now if I can just get it starting normally.

My 2008 Sonata finally let me down after 4-1/2 years of flawless service. Turned the key, it cranks fine, but won't start. I think it's the fuel pump. It has 63,000 miles now so the bumper-to-bimper warranty is over. Is the fuel pump (if that's it) covered by the 100,000 mile drive train warranty? I checked fuses and they are all fine. I don't know if there is a fuel cutoff switch. It might just be the pump relay...but I want to have it towed, and the choice is dealer or my regular mechanic.

It seems that I'm having issues with playing my IPod through my stereo on my '09 Sonata. I'm using the factory radio with the IPod connection in the console. I bought the cable from EBay. Sometimes the IPod will just pause and stop playing. Sometimes I have to unplug it and plug it back in to get it to work, other times I can just switch sources and switch back and it will work again. Also, isn't it supposed to charge the IPod also? I have left it for overnight a few times without unplugging it and when I came back in the morning, it would not play because it was dead. It did not even start to charge once I started the car up.

The last couple of times I've started the car from a cold start the RPM's fluctuate up and down for about 30 seconds and then it stops.

2009 Hyundai Sonata GLS 4cyl 135k miles...
Everything has been going fine. On Thursday I stopped at a gas station. Came out and the car won't start. Had it towed back to the house.
It cranks, but won't turn over.
Fuel pump kicks on.
Spark plugs were worn, so changed them, can't hurt.
They spark, although it looks like it may be weak.
After changing the spark plugs and trying to start it, pulled them and you can smell fuel, so it is getting into the engine.
Checked the connections of the wire harness (all I believe)
Anything specific to this model that would suddenly not run. I drove it 3 times that day, no problems starting, running, driving, anything. So I'm kind of stumped on the sudden development.
The check engine light had been on, but I did disconnect the battery when I was looking at something else before I checked the codes. So it isn't throwing any now.

'12 GLS with 45k on the odo. Keyed ignition, not a push button.
Did a 45000 mile recommended service, oil change with full synthetic, and throttle body service (cleanout) On Friday (July 3).
Drove it 70 miles on Saturday (July 4) with no problems...35 miles, sat for 10 hours, drive 35 more. 85 degrees outside and 60% humidity.
Drove it today (July 5) for ten miles, sat for 2 hours and 30 minutes. 87 degrees outside and 50% humidity.
Attempted to start after the 2.5 hours off. Starter cranked, but motor never caught and started. Tried five times. Nice crank (battery strong). Motor Still didn't catch. Third time motor almost caught, but it sputtered out.
Sixth time I let it crank for 7 seconds and it finally caught and started. CEL illuminated and stayed on all the way to the dealer (<1 mile from where I was) where left it for Monday diagnostics.
Spark should have been good.
Fuel and air were the unknown. TB service on Friday might make air the culprit. I also saw the high pressure fuel pump issue people reported. Not happy about having to possibly shell out 800-1100 for that! Also read about the oil starvation on the bearings, but the car exhibited no oil starvation symptoms (rattle, loss of power, etc).

I went to start the car today and it will turn over but doesn't start. I tried to see if it had any codes but not codes present. What should I try? It has 82k and I am original owner. What does the 100k warranty cover?

I have a 2009 Hyundai Sonata GLS 4 Cylinder with roughly 100k miles. The car runs great, shifts great, drives smooth. The only issue I have is starting the vehicle. When turning the key the car cranks sometimes longer than normal and sputters a bit before fully starting. I feel somewhat of a jolt like the engine is firing but its not what I call smooth. The other day it cranked longer than normal started for 1/2 a second then died and I had to turn the key again to start. I have already replaced the spark plugs and air filters. A while back we had the fuel filter/pump replaced but I'm not sure what else to do considering that the car runs fine otherwise. I read something about an EGR valve and maybe it's a vacuum hose?...

The fuse was not blown. The bus connection for that fuse was burned from a high capacitance caused when there is a loose connection.......period.

I have a 2009 Corolla 1.8L. It turns over but won't start. I don't hear the fuel pump when I turn the key on or when I try to start it. There are 3 EFI fuses, and all of them are good. There doesn't seem to be an EFI relay (correct me if I'm wrong). I've replaced the fuel pump and it still won't start.

I have a 09 camry 2.4. I have a problem with it starting about 5 times a year. It will start and shut back off and just keep doing this or just crank over. Then if we let it sit for about 15 minutes it will start and be fine for months. It's been doing this about 2 years. It has about 104,000 miles on it and there has never been any lights come on like the check engine light.

I have a 2010 Corolla LE w/ about 90k miles. I took it to work. parked. Went back to car. Engine cranks. Won't start. Lights are bright. Radio on. Jumped it and it started up no problem. Took it and got a brand new battery. turned car on and it worked with no problems. took it home. next day went to work. started w/ no problem. After work, started with no problem.
NEXT DAY... Engine cranks again....won't start. Tried to jump it again but NOTHING.
(also, just want to mention there is no history or indication that this was gonna happen. no jumpy starts...no shaking...nothing.)
Someone came out and checked: alternator, battery, starter, everything checks out good and working.
Spark plugs: GOOD but no spark...thought it might be crank sensor. Tried to change that out, still won't start.
In the midst of all this my key was acting up. finally it broke out of the lock part....the actual key separated (not broke) from the alarm part. i went to go make a duplicate w/ the key part and tried the duplicate key and it still won't start. do these things have a chip in them that activates the crank sensor? I've been w/o my car for about a week and i feel as though it's right in front of me.

I have a 2006 solara 3.3L. I bought this car about 4 months ago and it was running fine. Couple weeks ago I try to start the car and it would crank but won't start. I checked the fuel rails it was getting but somehow not starting... What can be the problem?

My 2008 Accent has a manual trans and 4-Cyl, 1.6L. It had some bad fuel 4 weeks ago, and filled the tank with 97 to clean it back up.
I was driving and came to a stop sign - the server stopped and wouldn't start up again. I was worried about the fuel pump, and ended up replacing the whole thing (under the passenger seat).
I have tested the following:
- When cranked, the bottom of the spark plugs are wet (so gas is getting to the plugs)
- When plugs are pulled out, they spark against the block (so spark should be getting to the cylinder).
The car still doesn't start, and the cranking sounds 'off'. I can't exactly describe what's wrong, but I've had it for six years and it doesn't sound right.
