Sonata NF (2006-10) :: LX Cranks But Won't Start (usually)
Nov 27, 2013
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.

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.

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.

'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?...

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.

I am having a problem starting my Escape. It ran fine when i parked it. Now it turns over but wont start.
It turns, almost catches, then turns slower. White smoke comes out of the exhaust, which means it is getting fuel i think. When I crank it all the dash warning lights go off. I tried the spare key. I tried pushing the gas pedal. No codes on the scanner. I switched the fuel relay (r3) with the fan relay (r4). I tilted the column a few times. Coils and wiring do not show any damage or wear. I opened the air filter with no change.
The only change i notice is that when turning the key has some resistance. It does not feel like it used to turn. This year I had to install a new battery and alternator. At 90k miles i gave it a tune up (plugs, boots and coils). It has 116k on it now.

My camry used to crank a couple of seconds longer and then take. Yesterday it died just after starting and wont start. It cranks. Checked and found fuse 15 in eng comp blown. Changed it and blew again. Check fuel pump, it seems to work when momentarily apply power to it. The engine management light does not come on when swithing ignition on any more as well. The airbag light also does not come on since this as well. Was wondering if ecu is gone bad?

My 2006 Azara has had a no start problem since about a year after we bough it new. The condition is intermittent and is not dependent on outside temperature, humidity or other conditions, It happens when the engine is cold or hot. Sometimes the problem goes away for a week or so then it comes back. It happens with either key.
The engine cranks over but does not start. Usually resolve it by sitting for 10 - 15 seconds then trying again. Sometimes have to do this two or three times before it fires. All other electrical items work ok and the battery has no problem powering accessories. I've had it into the dealer however because it is difficult to replicate, they have a hard time repairing the problem. The first time they neutralized the immobilizer and re-programmed it. The second time, I got a check engine light and they replaced the immobilizer. But the problem continues.

I just went out to move my truck to take out garbage and it cranks but doesn't start. It is 4.6L 4WD. I sprayed ether in intake no change. Checked all fuses all good. It has been raining pretty hard the last 3 days and it has been sitting in rain all 3 days. I checked for codes with a simple code scanner no codes. But the code scanner I used is not able to do KOEO or KOER tests. I know it needs new plugs but it has never sputtered or died on me. Has slight misfire but not engine stopping. I havnt had any check engine lights or problems before.

I have a 2006 6.0 that i did head gaskets on about a year ago. While I was in there I put some new pistons a valves in as well. I finished doing the job and it started and ran great just smoking a little bit. Test drove it a couple of times and still seemed great but still smoking. (white smoke) about a week went by with me driving the truck then one day driving to work I parked it then all of a sudden the truck shut off like some one hit the key and wouldn't restart after that. Either doesn't work i put a ficm in it before the head gaskets went out. new HPOP before head gaskets. I get oil pressure in the dash but it takes a long time to build up. cranks like a dream but doesn't even try to fire.

Bought a truck from a guy the other day. Long story, but he was a con artist. Told me the battery was dead from cranking it, he couldn't hear the fuel pump so he thinks it needs a new one. Got it home, checked fpdm, it was unplugged. Plugged it in fp running now. Charged battery. Cranks slowly won't start. Appears the engine has been changed. Have codes P0201-208, all injector codes. Cranking it over reminds me of an older distributor type engine that if off its timing. But also of cranking with a low battery. There's a new starter on it already. I'm going to pull the converter bolts on the weekend to see if they may have bound the torque when they installed the engine. Injector codes?

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.

Started right off in the morning, then parked it at the grocery store. Returned with groceries and car wouldn't start. Ran down battery trying. Called Tow Truck. Jumped, but no start still. Finally towed it home, recharged battery. Still no start. Gas tank 3/4 full. Then bought NAPA starting fluid, undid air cleaner intake area, sprayed 3 seconds (as directed), cranked, and car started. But died after spray no longer around. So, it seems to be a fuel problem. Fuel pump fuse OK. Is it the fuel pump, filter, so on...
