The IPR Valve on your 7.3L FORD Powerstroke is responsible for controlling the pressure in the high-pressure oil system which in turn operates the fuel injectors. The IPR (injection pressure regulator) is located on the high pressure oil pump at the front of the engine's valley. Due to the high pressures they are responsible for controlling, the IPR valve o-rings are a VERY common failure which will in turn result in low oil pressure related symptoms such as;


Poor idle
Stalling
No-start condition


While there are other potential causes, such as a failed IPR valve, the o-rings themselves are often at fault, and are much less expensive to replace. The IPR valve screen is another common failure. The screen may become plugged with debris and be collapsed by the flow of high pressure oil as it tries to flow through the restricted screen. A torn screen will allow debris to enter the IPR valve which may damage the valve.
