Hey all. Wealth of knowledge in these forums. Which I have consumed since I first got my truck running 2 years ago. Injectors back then.
2003 Ford F250 6.0 4x4
Crew Cab 235,000 miles
So after a 4000 mile round trip. On the way back I started to feel a slight miss during light acceleration under load, 60-70mph.
Got home. Hell froze over here. Plugged the oil heater in for 20 minutes. Fired up just fine. Little trip to the store. Idled in the parking lot for 20 min. Got on the road, accelerated just fine. Turned in to the neighborhood and accelerated around the turn. Died like the light switch had shut off. No bucking or missing, just turned off while accelerating.
Checked fuel in case of stuck gauge. Fuel filters looked as good as when I installed them. Secondary filter bowl is full.
Changed oil. Replaced oil filter. LPOP
is filling the oil filter canister.
Using OBDLink MX and Forscan these are my results:
Sync good. Cam / Crank Sensor check
- 49V on FICM
15% key on / 85% while cranking.
only reading 250 ~ 300 psi
desired 1900 psi
History of truck:
- Does not like being shut off for an hour or so and then trying to restart, long cranks to fire. But always fires.
- MOST NOTICEABLE: Small oil leak coming from the rear top of engine, coming down both sides of bell housing. When I left the store parking lot the day it died, that oil leak had become dime size to pancake size.
After checking readings with ForScan I performed the following:
- Disconnected ICP
sensor (sensor connector did have oil on it)
- Repaired damaged IPR
valve pigtail connector (bare copper on wires at connector)
New Readings on ForScan with ICP Sensor disconnected:
(desired 2179 psi
Next I will be pulling the IPR
valve to check the screen and actuate the plunger to see if it is stuck.
Question: I know the snap on fitting from the HPOP
tube on an 03' is a failure point. How do I know if HPOP
is actually bad or if the fittings are just leaking all over the place?
Thanks for any input!
