I looked at a 2006 truck that won't start. The owner said the dealer changed the LPOP due to failure and was told that the contamination migrated into the high psi system and has contaminated and ruined the injectors. If you watch desired vs actual icp it reaches 1500 psi at about 30% duty cycle on the IPR telling me the high psi system is healthy. Is it possible for the contamination to migrate that far? FICM voltage is 48.5v and the FICM goes into sync and you can hear the injectors pop.

 

Sounds like the high pressure oil system is working ok!? When the truck is turning over is there any smoke coming from the exhaust?
