02 wont maintaine OPOP

if i get on it easy it will get 2,300 to 2,800 Psi but if i get on it hard it will drop to 1,600 Psi then when i let off quick it will spike to 3,500.
so Im getting ICP lower then expected and then Im getting ICP higher then excepted. the truck has a new IPR and a new ICP sensor. My guess is the pump is shot. it has 189K on the clock. what is your guess??

08 F-350 crew cab Lariat 4X4 Dually auto 4:10 gears.

Is the IPR nut still securing the sensor to the shaft? I have found them missing, and the sensor slides up/down the IPR shaft on accel/decel...which gives me something else to look at on a buddy's truck I have been fighting, now that I type it. Kinda like writing down something so you don't forget to check it I guess...
