What is the engine serial number and are you getting check engine lights/stop engine lights .If so do you know the fault codes?

Customer: replied 6 months ago.
i'm getting lights flashing stop engine and the one time it shut down . but once it finally builds pressure it runs down the road at about 34- 36 psi without fluctuating . if the oil is hot after its been running and you shit it down and restart the pressure just if the oil gets down to that 0 degrees C or cooler it just seems like the gage won't come up . no codes show up when i look for them . i thought maybe the pump was weak or the regulator or relief , the one guy i asked about it figured its the oil thermostat in the cooler housing has likely broke loose and is moving around in side and there was a change up for that year of engine .or could it be as simple as a sending unit lol ? sorry i don't have the serial # on me i think the engine may have been built in 2007 cause the truck is 2008 w900 KW , the engine is set at 525hp with 1850 torq

if the oil pan is plugged in will come up pretty good but at 0 C out you shouldn't need the pan plugged in . even with the webasto on and the water temp is at 140 it doesn't seem to build pressure

the first step is hooking in a manual gauge to the engine.and hook up Cummins insite program to see what the sensor is reading and take both the manual gauge and Ecm reading to compare to the dash gauge. if you have the same readings on 2 setups than the one not reading the same is the problem . it could be as easy as a sender or gauge and not a real engine issue
