Ford F-250 Super Duty · 2005–2007
For the 2005 model year Ford revised the 6.0L's high-pressure oil pump and introduced a two-piece 'snap-to-connect' (STC) fitting on the HPOP branch tube. The two-piece fitting flexes with engine movement, wearing the internal seal and the locking ring until high-pressure oil leaks past it - or until the fitting separates outright. Because the HEUI injectors need roughly 500 psi of oil rail pressure to fire, the truck develops the classic pattern owners describe on the forums: it starts fine cold, then hot restarts get progressively longer, then one day it will not start at all after a fuel stop. It is one of the most common no-start causes on 2005-2007 trucks and is frequently misdiagnosed as injectors, a bad HPOP, or standpipes/dummy plugs (which fail with the same symptom set).
Common Symptoms
- Extended crank when hot, normal start when cold
- Sudden no-start after shutting the truck off warm
- Low or zero injection control pressure on a scan tool
- Engine cranks but never fires
- Rough running or dead miss under load
How to Fix
Install the updated Ford STC fitting kit, which includes the revised fitting, connector and a support bracket that stops the branch tube from moving - the bracket is the actual fix. The job is done under the turbo/intake with the HPOP cover off. While in there, most shops also replace the standpipes and dummy plugs, since they leak identically and the labor overlaps. No recall coverage; this is a customer-pay repair.

Frequently asked questions
What does P2290 mean?
P2290 stands for "Injector Control Pressure Too Low." Found on direct-injection diesel engines, this code means the actual injector control pressure is lower than the PCM commanded. Insufficient high-pressure oil/fuel to actuate the injectors leads to poor or no injection.
What are the most common causes of P2290?
The most common causes of P2290 are: Low engine oil level or pressure, Leaking high-pressure oil system or injector o-rings, Failed injection pressure regulator (IPR) valve, Weak high-pressure oil pump, Failed ICP sensor / wiring. The specific cause varies by vehicle.
How much does it cost to fix P2290?
Repair costs for P2290 range from $600 to $1,600, depending on the vehicle and root cause.
