Prius (2004-09) :: Electric Whirring Sound When AC Compressor Starts Running
I have a 2009 Prius with about 56K miles on it that I absolutely love. Now I know from reading in the forums an my own experience that when the A/C compressor starts running you hear an electric whirring sound. My question is... is it a cause for concern when the sound it makes seems different -- the pitch sounds lower to me now. The A/C still works fine, but I didn't know if this changing sound means the compressor was on the way out.

I have a 2001 f250 ext cab long bed 4x4 that I use as a feed pickup. I have had it for about a year now. one of the issues I have noticed since I bought it is the issue I am having with the flywheel/starter. Its very random like maybe I have a missing tooth or something on my fly wheel. but every so often when I would go to crank my truck over it would just make a little whirring sound and nothing happen ( like my starter gear isn't sliding out and engaging my fly wheel.
After looking through my inspection cover I noticed I had a little wear on the sides but no teeth to my knowledge broken or stripped off. I noticed my starter had one bold loose but other two perfectly tight. It was also covered in oil and dirt from my truck sweating horse power I decided to replace my starter and have my original ford starter rebuilt. I replaced it with a NEW oreillys starter. I noticed it cranked about 5 times as fast but again every 10-15 starts I am getting the same no start. any thing I am over looking?????
Ford 6.0L Power Stroke Diesel :: Random Hard Starts - No Power At Speed?
I have an 03 Excursion with 220,000 on the clock. Started getting harder starts randomly about a month ago, maybe a little more, pulled codes got p2290. Reset everything, changed the oil, oil filter, both fuel filters, eventually the ICP sensor itself and rebuilt the IPR with new screen kit and rings. Hard start went away for about a week but ICP pressure was dropping drastically during hard throttle or even trying to go up a good sized hill. I had a bypass oil filtration kit on and noticed that the connection on top of the oil filter housing was weeping at idle and leaking enough at throttle to possibly cause an issue. Replaced with new OEM filter cap and fill cap, and ended up with a no start and low ICP pressure.
Got it started today after a long crank (15+ seconds), ICP and IPR at idle both warm and cold are mid 600's and low 20's (I can get actuals if needed). After reaching operating temp starts fine after shut off (both immediate and after sitting for 20 minutes). I picked up a selection of parts and tools including an ICP air test tool. Also grabbed a hpop gasket kit and the updated O-rings for the whole system. Live scanning wise I have an Edge CTS and also an SCT x4 that I can use.
Ford 6.0L Power Stroke Diesel :: 2005 F350 - Engine Starts After Clicking Sound When Crank For Few Seconds
I am lost on what I need to do with my 2005 6.0. Last summer it started giving me trouble once in a while starting. I turn the key on and wait for the wait to start light to go out. When it goes out, turn the key and it starts, most of the time. Last summer I went to start it the same way, only it cranked and did not start. I turned the key off, back on and cycled the wait to start light again and turned to the start position, it started right up. Whenever it would act up I just turn the key off then back on and it starts right up. Usually on the second try, but lately it has taken 3 or more tries. I am not finding any real pattern to when it wont start.
When it does not start I can crank on the starter until the battery dies and it wont even think about starting. Turn the key off and back on, it will start.
Another thing I have noticed, when I crank the engine I can hear a clicking from under the hood right before it starts. I think it must have something to do with the injectors. I will crank the engine a few seconds, hear the clicking then it starts. If I don't hear the clicking it will not start, so when it doesn't want to start I also do not hear the clicking sound.
The other day I started it, drove 5 or 6 blocks and shut it off. After 20 minutes or so went to leave. I had to cycle the key 4 or 5 times off and back on before it decided to start. It is getting worse, doing it more frequently, and taking several times of key off and back on to get it going. Where should I start looking to find this problem?
Ford Excursion :: 2003 7.3L - Random Whirring Or Squealing Noise From The Front
I am now getting a random 'whirring' or 'squealing' noise from the front. When it starts, I feel some vibration in the steering wheel and floorboard and for sure can hear it. Starts on it own at random, sometimes when I hit a bump in the road. Stops at random, sometimes when hitting a bump in the road. Lasts for different lengths of time. Always stops when coming to a stop at about ~15 mph. Seems to change pitch ever so slightly if turning when it is 'whirring' or 'squealing'.

Went down to my garage after the Prius had been off for at least 5 hours and heard a whirring kind of like a fan in the back half of the vehicle. I had never heard this before and it went on for at least 5 minutes then quit. My garage was probably around 60 degrees for most of that time, fwiw. Seems like the area of the battery fan but why would that need to run?

View 3 RepliesPrius (2004-09) :: AC Starts To Make Whirring Noise And Just Won't Blow At All
So every once in a while, my A/C starts to sound like it's struggling. The force of the air gets stronger and weaker, and it starts to make a whirring noise (much louder than it should be). The temperature is fine, it's just the blowing air.
It will continue like this for weeks or months, then eventually when I start the car (particularly if I'm in my parking garage at work for some reason?!?! - could be a coincidence) the A/C won't blow at all. If I hold my hand near the vent, I can feel cold air - but it's just sitting there, not getting blown into the cabin.
Mitsubishi - Lancer :: Whirring / Growling Noise Starts Up A Second Or Two After Begin To Accelerate
Mitsubishi Lancer, 2003, 140k miles, auto transmission. About a week ago, I noticed a new noise coming from the engine compartment. It's not very loud, only a little louder than regular road/engine noise. It starts up a second or two after I begin to accelerate, and it winds down a second or two behind the rate at which I slow to a stop. It is constant when I am traveling at speed. The sound is something between a whirring and a growling noise, almost exactly the sound you hear when knobby bicycle tires roll quickly over smooth pavement.
The transmission fluid was about a quart low, and that got filled up, but the noise hasn't changed or stopped since then. I haven't had any problems with shifting out of/into gear. The car does occasionally "slip" out of gear in that when I am traveling slowly (stuck in traffic, usually) and going back and forth between light acceleration, coasting, and braking, once in a while I'll press the gas and the engine will just rev, but it won't engage. If I just let off the pedal, it will "reset" and then it moves just fine. It's done that ever since I bought the car in 2009, and it doesn't do it all that often, and only at those low traffic jam type speeds. So, I don't know if it's related to the noise, which is what I'm more concerned about.
4Runner/GX470 :: 1990 Toyota V6 Makes Whirring Noise When Key Is Turned But Engine Does Not Crank At All
I have an 1990 Toyota 4Runner. V6 engine. Automatic. 4wd. Today it blew an upper radiator hose. A few seconds after the initial pop of the hose and the spew of fluids the vehicle died. I replaced the upper radiator hose and the lower hose- and refilled the antifreeze. There are no leaks as of right now.
The engine will not start. The belts spin whenever the key is turned on. But the engine will not crank. You can hear the starter trying to start it up. Jumping the vehicle was of no luck. Charging the battery was of no dice.
The vehicle makes a whirring noise (belts spinning) when key is turned, but the engine does not crank at all. The noise stops as soon as you shut the key off. The oil is clean and full still.

View 5 RepliesGolf IV R32 :: Random Long Crank Usually Happens When It Is Really Cold
I was going to post this in the technical forum, but going by the amount of replies, this forum seems to have much more traffic. Anyway, my car has random long crank issues. It usually happens when it is really cold or if the car has sat for a day or more. I will have to hold the key over for 5+ seconds, but as soon as I turn the key back and crank again, it fires right up.
I have replaced the battery and tested it and the alternator, replaced the CTS (green top), not that it's relevant, but I just replaced the thermostat, housing and all seals, no CEL. Any other things I can check?
GTI 337/20th Anniversary :: GLI Won't Start At Random Times - No Crank
There wasn't even a crank. Held the ignition for a couple of seconds and it starts. The next day I had the battery and the alternator checked, they were both good. Another couple days passed and it did not want to start again. Got it scanned no codes come up. I changed the ignition switch and still I have the same problem with no crank.
View 8 RepliesAccent MC (2006-11) :: 2010 - Random Crank And No Start
I have been having this issue randomly, sometimes it won't occur for days and other times it happens in a short period. I will place my key in the ignition, and everything will chime correctly, and when I turn over my engine, it sounds like the engine catches then it just stalls. The things I have changed so far is,
battery ( needed to be changed anyways)
spark plugs ( was set to be changed)
air filter
cabin air filter ( no relevant but still...)
oil
At first I thought it could be bad gas, since I fill up sometimes at safeways etc, but in my tank right now is 91 octane shell, I thought it could be spark plugs since I was a little over due so I changed them, and the issue never popped up for 2 more weeks, then it came back.
if I use my car starter it seems to start better, but it is maybe 1 out of 10 times it will just crank continuously without catching or anything.
I can hear my fuel pump whirl when the key is turned but not started, I checked the oil today and it is full and a light color, maybe 500 km on this oil change.
Here is the youtube issue of what is happening... [URL] ......
I rather cover most of my bases without having to bring it in for servicing.

View 2 RepliesPassat (B5) :: Random Misfire Only At Idle / CEL Starts Flashing
Ok. Im going to keep this as short as possible. I bought my 05 passat 1.8t AWM TIP used in 09 with 44k
At around 90k I started getting a Random misfire only at idle. And it would be a different cylinder, not always the same would come back after clearing. The RPMs would be very low like around 840. And i think it should be around 920-960. That seems to be one of the main issues. Everything on the car is stock.
So basically, If my CEL starts flashing, and I clear it, I could drive a million miles with no misfires, but as soon as it starts to idle they come back ( I do have vag-com) and know how to use it for basic functions.
This is what has been done:
July 2011:
Engine rebuild (bad piston rings due to clogged cat converter)
Timing belt Kit (Timing was off 5 degrees!!!)
brand new turbo KO3, and Oil feed line
DV
N75 valve
Fuel Pump
Fuel Filter
Fuel Pressure regulator
MAF sensor
ECU swapped out (old ECU would not go through all steps for Throttle body alignment)
So, after all this and 3 weeks later, I get the car back and it ran great the whole way home. Put it in park waited 5 seconds, and the random misfires came back. So it went back to the shop the next day.
September 2011
These things were done:
Crank Position sensor
Cam position sensor
Compression test ( to make sure he didn't make a mistake while rebuilding motor) Results were Perfect
Leakdown test
Map sensor
Another MAF
2 O2 sensors
Upgraded DV
Fuel injectors
Removed engine wiring harness and OHMed every single wire. Nothing wrong
OEM Coilpacks
3 sets of copper plugs
Throttle body was swapped with 2 others from known working cars.
Trans pan replaced fluid flushed and new trans filter
I have heard this is a fairly common thing on the B5.5 models...
Eagle :: 1984 AMC - Turns Over But Engine Stops Running Unless Accelerator Kept Depressed
I recently acquired a 1984 AMC Eagle and I'm having trouble getting it to start. It turns over but the engine stops running unless the accelerator is kept depressed. Also, the car stalled at a light the one time I did get it running, so I'm thinking that there are some issues with the idle or with the carburetor maybe. I live in Colorado and I gather that the idle on these vehicles needed to get adjusted for the altitude, but I assume this has been done already as it has always been a Colorado car and has 125K miles on it. The gas is low, so possibly it might be something as simple as a gas supply issue, but judging by what other owners have posted online, it seems that this stalling problem is common with the Eagle so I think it probably is something more involved.
View 3 RepliesFord F-150 (2004-2008) :: 2006 - Random Crank But No Start Intermittently
I have a 2006 Ford Expedition with 95,000 miles that has a crank but intermittent no start problem. When it does happen, it will eventually start after one to two tries. I don't have to wait to start it again and I don't have any problems while it is running. Two or three times in the past two months it will sputter out and die (even though I am pressing the gas pedal) right after starting. I'll crank it again and it starts just fine. I have no problems while driving at freeway speeds or around town.
I never had any check engine lights come on so I replaced the battery and the fuel filter. I finally got two codes and replaced the fuel pump driver module and the fuel rail pressure sensor. The codes went off after replacing these two parts. I can hear my fuel pump turn on every time I start the vehicle. I have even taken the entire fuse panel apart to check Relay 303 which is soldered into the circuit board. It is fine and so is every other fuse in the panel.
Passat (B5) :: Whirring Sound From AC
We have had temps up in the 90's for the past couple of days so of course. I turned on the A/C in the Passat (03 GLS V6 tiptronic) and noticed that the A/C unit is really loud. Now by loud mean like a Whirring sound. It almost sounds like the turbine of a jet engine starting up. Now why I never noticed it before, I don't know (getting old and deaf I suppose) but I was wondering if everyone else's A/C is loud like a turbine or if maybe this is a premonition of a compressor meltdown.
