The most common cause of this is the IPR (Injector pressure regulator) goes bad or a leak at the high pressure oil system STC bracket at the high pressure pump or leaky dummy plugs. Verify base oil pressure by watching the oil pressure guage read half way when cranking it sometimes takes a while. If that guage reads 0psi the front cover groove behind the oil pump allowing oil to bypass and not build pressure also the pressure regulator could stick. If the oil guage reads half way when cranking you will need a scan to to monitor ICP (injector control pressure sensor) It should be .25 volts key on engine off and needs at least 500 psi pressure to start the truck. This repair is covered under the 5 year 100,000 miles diesel engine warranty. Send me the Vin# XXXXX mileage to verify coverage.
Leaving me a positive feedback is always appreciated, 100% positive feedback is my goal. If you feel that the answer was able to save you significant time and money bonuses are also appreciated.
P2285 ICP pressure low (because of a leak in the high pressure oil system)
P0197 and P0198 looks like a bad oil temp sensor I would replace it. Should be pretty cheap.
Monitor ICP should be .2 volts Key on engine off about 1.0V cranking if it stays at .2V normally about .24V when cranking it means it is not building up high pressure oil It needs 500-600 psi to start runs off(NNN) NNN-NNNNsi. At 4000 psi o-rings or fittings blow apart then you have a leak. Leak in the high pressure oil system no start.
