stalls when turning wheel hard
My bronco will stall when I turn the wheel all the way to left or right, she will do this when the truck is in motion and also when she is in the driveway. I put her in park and turn thewheel hard-stalll, the same thing for R, N, D etc. I was told once that it could be the pressure sensor on the power steering pump, I asked at the local ford dealership and they said my 1982 Bronco was too early a year to have a pressure sensor, is this true or did I tell them the wrong thing. I would appreciate if someone could tell me if a 1982 Bronco does have a pressure sesnor and also what else could be causing the bronco to stall like this. Any help would be appeciated.

my 84 does it oo
only when i cut it all the way and hold it. Doesnt always stall, but engine will always make a bobble. Dont know why, it runs too good for the load of the pump to cause it to stall

stalling when turning wheel while backing up.
I'm having same problem. Only seems to do it when backing up while turning wheel sharp. Not sure what it is, I do notice that when I turn the wheel some times I here a noise from the power steering and it feels alittle choppy just sitting while turning it.

all of the problems that you guys are talking about sounds like a bad pump. once the internal bearings start to go then it puts more wear and tear. Now I AM NOT SAYING FOR SURE that it is your pump but thats what it sounds like to me. One more thing is do you have the stock tires with out lift or larger tires with out lift of lift with tires?

a whining pump, when full of fluid, is prob a bad pump. As for the engine stalling when the wheel is turned all the way, sounds like your idle might be to low, and the load of the power steering pump might be too much, then kills it. what is your idle at?, in gear, and not.

MDS01 said that it did it no matter what gear he was in moving or not. personally i would go out and buy a pump and if it isn't it they either you have a new pump or you clean it real well and return it

I get the whining sound also, my idle seems to be ok I actually always thought my idle may be a bit on the high side, as for pirocat29 question: I have 15" 31X10.5 tires without lift, I was kind of swinging torwards replacing the power steering pump, is that a hard job, I ve never done it, and anything I should now about before I do it, I do know I will have to get one of those pulleys? is that correct, thanks for all your suggestions!

All ford pumps wine. unless you did a saginaw pump swap. if its dieing like this i would start with a tune up, cap, rotor, wires, plugs and fuel filter. also check timing should be at 10* btdc. check your belts to see if they are worn or to tight. you might think about putting new fluid in the powersteering pump. if its old that to could cause a problem.
good luck

Same problem
Have a problem with my 78 f100, When I try to make sharp turn in either direction it kills the engine. I have replaced the entire steering system: steering pump and box including hoses. Had to even replace the new steering box due to a defect. Someone told me that it could be a ground problem. Does anyone have any other ideas, that may be helpful? I have already done a complete tune up. Checked and rechecked the timing. I’ve replaced the battery, coil, coil cap, cylinoid(sorry bout spelling), voltage regulator, and elec. ignition module. At wits end.

two things
Two things are at play here.
One is that your power steering pump is really putting out a load.
Two is that your engine is not running strong enough to handle the load.
Make sure your idle is high enough. Replace the PS pump if you have not. Try loosening the PS pump belt, get it pretty sloppy and try the test again.
If it were an electrical issue it most likely would not do it in both directions. It would also cut off like you turned the switch, vs a load drag which will pull the engine down until it dies.
Put the front end on jack stands so the wheels are just off the ground. Turn the wheel all the way to the left slowly. My guess is that you will hear the pump when it bottoms out and any turning past that kills the engine. This means that the poppet valve is stuck or boroken inside, or the wheel are bottoming out before the poppet valve reaches full travel and cuts the pressure.
