2003 i dont know how to test pump or stc tube
Expert:  Ron replied 4 years ago.
In most cases this code is set due to a failing high pressure oil pump , are you trying to install a new one? You need at least 500 PSI of oil pressure to fire your injectors. The best way to test the pump is to monitor you IPC (injector control pressure)signel while cranking. A normal reading is about 1200 PSI.

is this done on or off the truck how do i know if the pump is bad or stc losing pressure
Expert:  Ron replied 4 years ago.
The test is done on the truck, you monitor the IPC single while cranking.

I have enclosed the Factory Pinpoint test for both codes. This should help .
