02 f450 starts, runs great, dies after 15-25 mins
Whats up everyone, got a f450 givin me some trouble. I can start the vehicle when it is cold and it will run for aproximately 15 to 25 mins. During this period, high pressure oil is fluctuating between 470 and 500 psi. Have replace the icp and removed the ipr, resealed and cleaned it. It still does the same thing. Performed koeo test and code p1283 ipr circuit failure. No metal flakes in oil, have wiggled wires while trying to start and while it is running and nothing causes it to die. When the vehicle dies, the high pressure oil falls to 25psi and stays at 25psi even when the engine isn't running. Then while trying to start it again, the oil pressure will not exceed above 200psi during cranking. Give the truck 30mins and will start again. And i also noticed the coolant temp on the computer was fluctuating between
5f to 520f which is crazy. I looked for the coolant temp sensor for the computer and couldnt find it anywhere. I talked to someone and they said it didnt have one but i looked on alldata and it says it has one. I am offically stumped. If anyone has experienced this problem or similar please let me know what you did to solve this problem. Thanks Everyone
