Passat (B6) :: Car Has Difficult Cold Start
Nov 1, 2013
Car is at the stealership right now 74k miles (CPO until 75k). Having issues with cold starts, weather has been getting into the 40's, and when coming out of work in the ramp the car has a very hard time starting (usually taking 3 times to fully turn over). However, in the morning coming out of my heated garage the car starts right up no problems whatsoever.
There are zero codes being thrown, zero lights on the dash. Brought the car in for diagnosis and the dealer has had it now for 2 days - still "unsure of the issue" but they have proposed that it is either a fuel pump (covered by CPO) or Carbon-Build up.

My 97 Subaru sport has trouble starting when left until cold, it always finally starts, but wont rev at all until its has been running for 20-30 seconds.
Other symptoms include....Once running it also seems to be lacking power across the low rev range. but then seems fine above 4k rpm.
If i get stuck in stationary traffic for a while, the check engine light comes on and i lose all power, it hardly pulls its self off to a start. But if i were to rev the engine and let it drop back to idle a couple of times the light goes off and i get power back to set off.

I have cleaned the fuel injectors, put in new spark plugs and new spark plug wires. What else I can do. The only time it starts easily is when it's very hot. If I leave it off for just 5 minutes, it will start up quickly. And a few times, when it is dead cold it will start on the first turn. All other times I have to crank it for what seems like minutes. I'm killing batteries and starters on a regular basis.

I have a 2004 Passat V6. Couple of weeks ago the check engine light went on. I went to AutoZone and checked. The code read P3081 (low engine temperature). I knew it might be caused by bad coolant temp sensor or T-Stat sensor. I also experienced that the engine would not start occasionally (prior and post the light on).
My question is that whether the low engine temperature can cause the difficulty to start the engine? How can I figure out which sensor is bad?

I have a 2009 Acura TSX that I bought used ~85,000 miles on it. It has been inspected 5 times and each mechanic says the car is basically new in perfect condition. However, it has an extremely difficult time starting after sitting in cold temperatures for more than about 12 hours. If I drive it every 8 hours or so it is fine. Everything has been checked repeatedly; alternator, wiring, battery connection etc. .. . The battery is only 3 months old.

Had an interesting problem with my 2006 Camry (134k miles - all maintenance up to date). After returning from trip, I went to start my 2006 Camry LE and it turned over but never started. After a couple more tries, I stepped on the accelerator while turning the key and it finally started. It's starting and running fine now but that is the first time that has ever happened. The car sat for 5 days.

The check engine light is on. Yesterday twice I had the situation where when I turned the key to start. The starter motor was crankin and it was not firing. I pumped the throttle a few times to let air/gas into engine. I also opened the gasoline tank cover (where you insert the nozzle to pump gas) for a few mins and then shut it and started the car. It started. After running for 20 mins it happened again. The starter motor has to crank for some 10 seconds before it fires. Then no issues. What do you think it is??? Battery is fine, starter motor is fine since its cranking away. I am suspecting fuel pump ?

I went to check out a TDI. Got there and it had to be jumped (45F) The glow plug harness was bad. but even after we got it started and drove it for several miles to get it to operating temp, it was still difficult to start after shutting it off. Shouldn't it start up easily after being warmed up even if the glow plug harness was bad?

I'm having an issue with my 08 Accent GS. It is very difficult to start, but only after fueling. Any other time, the car starts without any problems. I have tried to simulate the issue at home by taking off the gas cap and replacing it, but it didn't have the same result.

2006 Kia Rio LX with 78K miles,
I recently performed several repairs in the car including replacement of the timing belt, all other drive belts (power steering, air conditioning, alternator).
Recently, the car has developed a new problem where it intermittently has been difficult to start, but only after filling up the gas tank. The engine cranks over okay but it seems like it might have vapor lock. It seems to occur every time we fill it up. Rarely, the car has appeared to run rough for a few seconds, the electronic control module seems to make an adjustment and then it runs better. The gas mileage has decreased from typical 28-32 miles a gallon down to 23-25 miles per gallon, despite getting new tires for the car.
Additionally, the check engine light has come on intermittently…once reset it stays off for up to two weeks then will come back intermittently with the following codes:
P0456 which indicates a problem with the fuel evaporation system, which may be related to the gas cap (sometimes when this comes on, the gas cap appears to be loose, but other times it appears to be tight).
P0300 which indicates in engine misfireP0301 which indicates in engine misfire in cylinder #1P0302 which indicates in engine misfire in cylinder #2The first time that I received this warning, I replaced the 4 spark plugs and the check engine light did not come back on for a couple weeks.
I have also previously received a code for faulty oxygen sensor temperature regulation for the forward most oxygen sensor. From what I have read, this may be related to oxygen sensors were related to an exhaust or intake leak. I have attempted to carefully inspect the intake and exhaust systems and I don't find evidence of leak. (From what I have read, a lean fuel condition which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open are possible causes.
I have visually inspected the 4 coils/plug wire units and they all appear to be intact and since the engine does not run rough (it idles smoothly, seems to have normal power etc.), I believe that they're all functioning.Any thoughts about what should be my next step to diagnose and to fix this problem?Replace gas cap?Replace oxygen sensors?EGR valve?Could this be related to the timing belt replacement (CEL did come on prior to the repair but gas mileage and problem starting after fill-up has started after the change)? Carbon canister or solenoid valve for evap emissions needs replacement?(I have never been in the habit of "topping off the tank").

Symptoms:
- Check engine light: misfire on all cylinders, and "lean fuel trim at part throttle".
Started with changing leads and plugs without improvement. Then I found the tank ventilation seemed to be clogged, as there was a massive vacuum when opening the filler cap. Checked the canister and replaced a couple of corroded lines. Also used compressed air to blow through the canister and lines up to the Evap-purge valve. Seemed to be OK afterwards (no vacuum), but still misfires.
Changed the Mass Air flow sensor, and it seems the misfires got better, but instead I have some other issues:
- Hard to start when cold. Starts up fine for a second then sounds like it's getting to much fuel and dies. Possible to keep it running if pumping the pedal or holding it at higher revs.
- Rough idle when warm. (Same as before I changed the MAF and plugs/ leads.)
- Drives and runs ok when out on the road.
- Pulled the cable to the Idle Control Valve without any change in idle...?
- Got flashing engine light and "misfire cylinder 4" when giving full throttle on low revs and seond gear up a steep climb.
What could cause this?
- Temperature sensor?
- O2-sensor?
- Idle control valve?
- Coilpack?

2012 Golf GTI, bone stock, 18k miles. The issue is pretty straightforward. It takes longer to crank than I feel it should, perhaps 5-6 seconds, sometimes the car is cold, sometimes warm. Sometimes it cranks right up with no issue. A VCDS scan is clean. This is Atlanta weather too, so the temps are pretty mild.

Recently my 2001 F150 4x4 5.4 truck has been misbehaving by being difficult to start at random times. The engine will turn over with however will not fire. After some time, I am able to get it to fire. When this happens the truck start normally for the rest of the day and maybe several days. Around the same time, error codes for a variety of sensors would occur. This problem was traced to a broken PCM connection. When this problem does materialize, no error codes are generated. After some time in repair shop, a probable cause could not be found.

1995 aero, 4.0 auto AWD. wouldn't start about a month ago and got parked. got around to working on it and it would start and run a couple seconds then just crank and crank, I tossed another edis module on it that i had with no change, tried it without the MAF plugged in, had consistent spark while cranking. fuel pump would prime just fine. after a while I was experimenting around and held the throttle WOT and got a couple coughs.
after a while of cranking and trying different stuff I had began to get a few backfires (and by this time i had the spout and the octane plug out) and I was actually trying to see if i could see backfires out the tail pipe cause i couldn't determine if they were intake or exhaust side, it finally started. it ran really rough and coughed and sputtered and backfired a few times, then after about 30 seconds it smoothed out and started idling like normal.
I took it for a drive and it ran normal, so i shut it off and reinstalled the spout and octane plug and took it for another drive and it ran better (assuming the ign advance is working, so it must not be in limp home mode)
When I first started I pulled codes 114 and 118, ACT sensor out of range and ECT voltage high (Note: when I got it started the gauge didn't show it as being very "warmed up" even though it idled about 30 minutes before I drove it about 10 miles). I am gonna let it cool for the night and see how it starts in the morning, then try pulling codes again...

I have a 1998 Explorer XLT with the 4.0 sohc engine.
Recently the truck started being difficult to start and takes a few times of cranking to get it going. Once running, it idles and drives fine on city streets and freeways. When trying to start it turns over fine but doesn't start. After a few times of that, it will finally start. Sometimes it will sputter out an die but then it will start right away and be fine.
It never starts right away when cold and when hot or after short trips its intermittent...Sometimes it will start right up...others it takes a time or two of cranking. I just replaced the fuel filter and it did not work. I am thinking the fuel pump but since its in the tank, I am hoping its not that.

My '08 2.7 has difficulty starting in the morning. It makes the normal cranking noises but won't fire up immediately. I typically let it try to catch for 5-10 seconds, pause, and try again. Then I wait a minute, try again, and everything starts fine. Then it'll start normally the rest of the day.
Pardon my ignorance, but isn't there some sort of compartment that holds fuel into the engine with a check valve that keeps it from releasing back into the tank? Could it be that this valve is leaking?
Or does it sound like I need a whole new fuel pump? I tried to find schematics, but had no luck. I tired hmaservice.com, but I'm not willing to install the Adobe SVG app (obsolete and security risk) to view the documents.

This noise started a few days ago. Only happens when the car has sat overnight, and only for about a minute or so. This is a 2005 1.8T with about 116K miles, timing belt done at 108K, AC compressor replaced in June. Oil changed every 5k with Mobil 1 0W40 - All filters and spark plugs replaced at 105K. Car is in Florida, temperatures are about 78-85F in the morning.

The rattle only lasts for a second or two. Only warning light recently was airbag control module, addressed by Dealer. Also noticed recently, while doing some "spirited" driving, there was a deep-bass thump sound at the end of each gear change.
I've done forum searches for start-up rattle and found issues with timing chain/belt, in relation to the tensioner bolt, mentioned in reference to an earlier design(?). I was unable to find anything related to the B7/NMS.
No idea if it's a V6 issue, DSG issue or general VW issue. NMS V6? NMS DSG?

Bought a 2006 (later production) with 25,000 miles over the weekend. Couldn't pass up the price and the warranty (1 year left + CPO). Picked up the car Saturday at noon..... had to drive to DC for business and the CEL came on when I turned on the car this morning. I researched at lunch that it could be a cold start misfire but I am already pretty heated about this. When I get home tonight I am going to plug it in to my OBDII scanner and see what I can pull. If it is something bad.... I am giving it back to the dealership.

My 2013 Passat SEL TDI has 40,000 miles on the clock and in the past few months I've noticed it's taking longer to start blowing cold air. I've had several summers already so I'm already used to it's performance in the hot summer months but this summer has been different. The A/C will not blow any cold air at all before the car gets going under load (it didn't need engine load before) and sometimes it just won't blow cold at all but just barely "cool" air. I'll sometimes be driving for a half hour and never get the A/C to really blow cold.
Other times, it'll blow just fine. It's the hit and miss performance that has me confused. I then bought one of those refrigerant bottles from an auto parts store that comes with a gauge to see if maybe I have lost refrigerant or it's low but when I checked the gauge the pressure was exactly where it needed to be. I just came off that dreaded 40K service at the dealership and am trying to avoid going back there at all costs...

Check out how loud my cold start idle is. Still can't figure out why you can't hear the turbo on start up though. Even revving at idle you can't hear it that much. I've seen plenty of gti's with more exhaust restriction then i have and you can hear it clearly. [URL] .....
