you mean squealing/screeching? is it serpentine belt? they can look ok but still be worn out. the grooves wear too wide and bottom out and slip.

alternator is ok took it to autozone. There is a recall on the Fuel Pressure Regulator could this be the problem. If not when they fix the recall I will have them check the serpentine belt.
