How to test the high pressure oil pump?
If you have no oil pressure on the dash gauge you need to drop the tin sump under the engine and check the two oil pick up pipes in there . They crack and fall off or the seal goes hard letting in air so no oil pumps. An known fault on the 3.0
The long one is for the engine oil lube ( turbo ) and the short one is for the injection system .
The high pressure pump is only for the injectors.
If you have good oil pressure on the dash gauge then I agree with Guru Ronaldbrains the turbos are poor but ! its 5/30 oil in 3.0 4JX1 engine or you will have starting troubles .

I had the trooper in for an oil change and emmissions check. Next day, it almost stalled. After a couple trips, it started to stall every time it stopped and I tried to start up again.
Turned out, the tubing coming out of the MAF has a hose clamp around it. That hose clamp could freely spin around. I tightened it up. The truck started running better. And after 3-4 trips, the codes cleared themselves.
Reading about it, there are a lot more causes, but this was apparently mine. IDK why it was loose. Something at the inspection place. Maybe they did it on purpose because they wanted nearly $80 to replace the fuel filter (a $10 part) and I refused.
