#173 of 180 Re: 04 Z71 Tahoe whirring noise [ereddish] by kiawah Oct 16, 2009 (6:03 am)
Replying to: ereddish (Oct 16, 2009 5:35 am) About the only suggestion I could make, is have someone ride with you in the back seat with the windows down. Compare the noise by listening out the right window, with that out the left window. If the sound is the same intensity, then I'm guessing it would be from the transmission (in the middle of the car), versus a wheel (clearly on one side of the car).   If it's on the side, then try to pick up whether it's coming from the front, or back.

Replying to: oldjoe70 (Aug 19, 2009 4:23 pm) I have seen several people in this thread with the same issue of no crank. I too can wiggle the wire and it seems to make it start. It odesnt make sense though because I have checked and rechecked connections. The only thing that sounds like a possibilty is the starter solenoid or the park switch. Noone has actually said what fixed this problem though...anyone?? I am going to check the shift lever next time it happens! Replies to this message: rslawsky (Oct 19, 2009 12:13 pm)

Replying to: 1flyinz (Oct 19, 2009 11:58 am) I switched to a new key and that seemed to cure it, although it did happen once with the new key. Hasn't happened in months, though.

Replying to: ereddish (Oct 16, 2009 5:35 am) I was wondering if you have mud grips. They are known to make a whirring noise. Other than that, one would assume possibly a bearing in a sealed hub or a brake tab if they believe the noise is from a wheel, but not always. If you have vibration when you drive, it could be a fault in a new tire (out of round condition). Another overlooked item is the u-joints on the driveshaft. Roll down your window, put your vehicle in drive, and let it roll freely. See if you can isolate the noise. If the noise starts right off and gets louder as the vehicle freely speeds up, it may be your u-joints. Get under the vehicle and work your driveshaft back and forth. If there is any free play, they need to be replaced. But of course, try to isolate the noise. Hope it helps, Ernie.
#177 of 180 Starting Issue 2000 Suburban by semperteneo Nov 12, 2009 (11:34 am)
Friend's Suburban is a 2000.   Recently installed a starter and a "resistor." Not 100% sure what the deal was with resistor, but those are the only recent changes to vehicle.   Post-starter install it's been fine for him. However, he got a code and had another friend plug in the scanner to find out what it was.   Now, his "tow" light comes on whenever he starts the car and has a starting issue. From what I understand, every time the truck is started (regardless of cold or warm start) it takes a while to start. It does start, but from what he described it was like a slow start.   Is there anything that would cause the "tow" light to come on and also cause the weak start?   Not familiar with the suburbans, but can get whatever info may help...
#178 of 180 02 Tahoe starting problems by jstroos Nov 15, 2009 (3:25 pm)
My 2002 Chevy Tahoe is having intermittent problems with starting. Engine cranks but won't start. Takes multiple attempts to start and when it does fire it does stay running unless I start to lightly feather in gas by depressing the gas pedal (I know this is not recommended.) The engine will run poorly and then idle down below 500 RPM's amost to the point of stalling. In the last 6 months I have replaced fuel filter, air filter, fuel pump, battery. there are no DTC's in the computer. it is a 4.8L V-8.   What is really odd is that the problem has occured on two different situations: 1.) Most recently on a return from an extended vacation (>5 days) the car would not start or stay running at idle 2.) a quick stop at a store for 5 minutes, return to vehicle and it will not start or stay running.   The fuel rail losing pressure sounds likely but the fuel pressure regulator does NOT have gas in the vacuum line and each situation above seems like they are mutually exclusive.   Thanks Jeff Replies to this message: us2bamechanic (Dec 04, 2009 7:57 pm)

Replying to: jstroos (Nov 15, 2009 3:25 pm) Did you every get a response on what the problem may be? We are having similar problems with our Tahoe same year. Curious as to what the outcome was. Joe
