The part in the picture below is the HPOP oil rail that sits on top of the injectors, which are computer controlled by a separate module called a FICM (Fuel Injection Control Module). The Powertrain Control Module (PCM) sends commands to the Injection Pressure Regulator (IPR) to modulate the amount of oil pressure in the rails that act on the injectors to force fuel into the cylinders at up 40,000 psi!

Mobile Mechanic says “Oil is the life blood, change it often!”

These trucks will not start if they are too low on oil, or if there are leaks in the HPOP system. Also maintenance is CRITICAL! Do oil changes every 5,000 miles religiously! Even if you use Synthetic oil, extended oil change intervals are NOT recommended.
Dirty oil damages the internal components and can greatly accelerate failure of the HPOP systems seals and IPR. Another common problem is the screen in the oil sump below the oil filter housing, the screen deteriorates and pieces of it get sucked into the HPOP damaging the pump and the IPR.
There are updated components to replace some of the common failure items, the right Mobile Mechanic can keep you up and running wherever you are, from south orange county, to Ventura, Malibu, Thousand Oaks, Newbury Park, Moorpark, Irvine, Anaheim, Huntington Beach, etc, yu get the idea, pretty much from south OC to the north through LA, Long Beach and along the 101 west into Ventura County.
