The other day I was pulling into a parking space and I had the wheel turned to full lock and the motor just shut off on me. This is the 4th or 5th time this has happend in the last 3 months or so but I can't figure out why it happens. It only happens when I have the wheel turned to full lock, usually pulling into a parking space (so i'm going around 5mph or so). I have no trouble restarting the car after it shuts off. I drive a 2000 Yukon XL with 95k miles on it, but the car is in good shape and has had no other mechanical problems. Does anybody know why this is happening?

wild guess

power steering pulley bearings going bad and stopping the engine at load

I say this 'cause my old alternator had seized up enough to where it was keeping the engine from turning

Since what?

3/1/2006 2:00:07 PM

since when?

how low is your gas? might seem silly, but a valid question. the gas could splash over and stall your engine. as said above, might be due to the power steering assembly.

My gas gauge pretty much always stays below half (usually between empty and a 1/4, I figure less weight = better gas mileage).

^The link above was helpful but it didn't really answer the question. Could this really be an issue with the PCM? It would seem to me that if the PCM is the problem than this would happen regardless of the position of the steering wheel, but I don't know. I'm thinking it has something to do with power steering too, but that's just a semi-educated guess.

and i meant sense for all you grammer nazi's out there

Do those trucks use a power steering pressure switch? If so, I'd start there.

I dont mean to nerd it up in here or anything, but it wouldnt take much to prove or disprove this using basic middle school scientific method. My ghost tells me your "figuring" is wrong.

internal pressure relief valve in the pump ain't relieving.

a gallon of gas is a little over 6 lbs.

sense...there ya go.


^^i've thought about that before, but i figure it's way more trouble than it's worth. i mean, you could actually calculate out what you'd save, given some engine and vehicle parameters...but that's more trouble than it's worth, too.

Please, elaborate...

^nevermind, I'm going to start a new post about this. I'd like to hear more opinions on this theory of less gas = better/worse mpg.

3/2/2006 9:47:09 AM

^ my 01 silverado does the same thing, its just a high mileage chevy thing, if you quickly let off the gas immiediatly before a full turn, the rpms dip too low before the iac can recover and it cuts off. cleaning the throttle body and intake helps a lot with this problem. also if you have the 5.3 or 4.8, and the pedal sticks at idle, polishing the inside of the throttle body where the butterfly rests with 400 grit sandpaper will help.

umm no, i dont feel like looking it up, but any fuel oil will not be denser the 8.34#/gal
