1999 Jeep Wrangler 2.5l, manual transmission. My jeep has started making a new noise. Seems to have popped up as it got cold and the colder it is the more I notice it. When I first start it up (cold morning) there is a load "whirling" sound. Sounds to me like something thats spinning. When I push in on the clutch it doesn't stop, but the "tone" of the whirling changes. Not louder or quieter, just s differnent tone. Seems to run fine (for now) and once the engine warms up it stops. If I leave my house and stop 3-4 miles away at the store, by the time I get to the store it's not doing it anymore. Any ideas?

I had the same problem at about the same mileage. Replaced the power steering pump and the start up screaming went away! ( The Jeep's and mine!)

yes, sounds like the starter solinoid whent out, if it shorts out it can stay running, it must be replaced ,there is no quick fix, if its a manual trans you can push start it. i dont know of any internet tips.

Could be one of several items...I'd check the fuel pump relay, auto shutdown relay and the ignition switch itself. I'd bet on it being one of those relays but, we all have been fooled at least once!!! I'd also make sure that body and engine grounding is good and clean. Relays can't work properly without a good ground.
