I have a 2002 F350 with 264k miles that i have been troubleshooting an issue with poor performance. It is stock with an intake 4 inch down pipe and 5 inch exhaust Hutch & Harpoon mod no programmer or chip but had superchip tune when i bought it i returned it to stock and sold that. Also had 10k resistor mod when i bought it but it has been disconnected.
About 6 months ago i could do a 0-60 run and would get a CEL P1211 and and my ICP would be 2k+, lately i have been watching it and it is getting worse. I tried to do a 0-60 today leaving a stoplight and gave up when the ICP went down to 800ish. i have attached 2 data logs one was from October 0-60 and one from today. Today i checked the codes and had a 1211 and 1209. I have been driving easy but it is getting to where i can get a CEL if i try to go 50% throttle for any period of time.
I need to replace my glow plugs so the valve covers have to come off it will be my first time pulling them, so at that point i can run it with the covers off to see what the injectors are doing. If it matters i checked my IPR and ICP sensor tonight neither have oil on connector and the nut on IPR is tight. I have the right amount of oil im using T6 and it has about 3k miles on it, no boost leaks either.
My Questions
1, Could low fuel pressure cause low ICP? I dont have a fuel pressure gauge but am trying to rule out easy first.
2. Could Injector Orings leak bad enough to cause pressure to go that low?
From what I described would it lead you to believe it is Injectors, Orings, HPOP, Fuel pressure, or something else?
Im on a tight budget but have some money available to fix this i just dont want to buy parts that are not needed or dont help.
Sorry for the novel. Im hoping for a sure way to verify what needs to be replaced.
