ok says injector pressure sensor low first guess was the upgrade to the blue spring. did that code clear for a day then comes back on looking at the hfcm but kinda unsure where to look anyone with this experience ?? came on after we got the real cold snap and i had to buy a block heater i dont see one on here i also added diesel 911 to the tank this is a 05 f250 w 6.0l

 

Injection pressure had nothing to do with the fuel side of the system. It refers to the high pressure oil system. On an 05 the most common things are the stc fitting, and dummy plugs, stand pipes. That's if you icp sensor is good. Are very difficult to do but ate time consuming. You do need a way to read live data to pinpoint the problem. Stop over to the 6.0 section and read some of the tech folders. It will help you understand how things work and give you the info to get the right parts.

 

damn i just had the orings done thanks
