[QUOTE="bigwheel, post: 142913, member: 1244"] So I worked on swaping out the IPR last night to one that is used but came out of another running truck. Once I got it swaped I checked the HPOP level which was low so I put in about a 1qt of oil, seemed like a lot. Can you over fill them? So after I thought it might be close to full I tried to start the truck. After a few trys the truck didn't sound like it was wanting to start. Hook up the code reader to find alot of them. KOEO found: P1280- Injector control pressure sensor circuit low P0472- Exhaust Pressure sensor low input P0198- Engine air temp sensor high input P1119- Manifold ait temp circuit high input P0380- Glowplug heater circuit A P1212- Injector control pressure not at expected level P0640- Intake air heater control circuit So I am thinking that it might not be picking up the IPR or the ICP might be bad now. Might try switching back out to the old IPR and see if there is a change. Any thoughts? [/QUOTE]
