- Hard start or no start
- Loss of power / limp mode
- CEL
- Metal debris in fuel rails (if CP4 has grenaded)
What Causes POWERSTROKE-P0087-67? (Most Likely First)
- CP4 high-pressure fuel pump failure (catastrophic; the Bosch CP4.2 ran the entire 6.7L line, 2011-present) Very Likely
- Plugged fuel filter Likely
- Failed fuel pressure sensor Likely
- Leaking fuel injector (returning excess fuel) Possible
Can I Still Drive with POWERSTROKE-P0087-67?
No — stop driving. POWERSTROKE-P0087-67 is rated serious severity. Continuing to drive in this state risks further damage — get it looked at before your next trip.
Common Fixes by Vehicle

2011-2019 Ford F-250/F-350 6.7L Power Stroke Advanced DIY
P0087 on the 6.7L Scorpion is the Bosch CP4.2 pump failure -- same catastrophic mode as the Duramax LML. When the CP4 fails, metal grinds through the entire fuel system. Do NOT drive the truck. Full replacement at a dealer runs $8,000-$14,000. S&S Diesel Motorsport and other vendors offer CP3 conversion kits ($3,500-$5,500) which are the permanent fix most 6.7L owners pursue. Catch-can kits do NOT prevent failure.
Labor: 10-14 hours (full system)Frequently Asked Questions
What causes CP4 failure on the 6.7 Power Stroke?
The Bosch CP4.2 pump used on 2011-present 6.7L trucks has marginal self-lubrication. When fuel lubricity is poor or the cam follower slips, the cam scuffs into the pump body and sends metal downstream. US diesel fuel lubricity is on the low side of what the pump was designed for.
How do I know if my CP4 has grenaded?
Drain the fuel filter housings and inspect for metallic glitter under a magnet. If metal is present, assume the pump failed and do NOT restart the engine -- every crank pushes more debris into the injectors.
Is a CP3 conversion worth it?
Most owners doing a CP4 repair install a CP3 conversion at the same time. It adds $1,000-$2,000 to an already $8,000+ repair and is widely considered permanent prevention. It does require a tuner/programmer.
Mechanics Guide Step-by-step diagnosis
How Do You Diagnose POWERSTROKE-P0087-67?
DO NOT start the engine if you suspect CP4 failure -- metal debris will destroy all 8 injectors + rails.
Pull the fuel filter housing drain and inspect for metallic glitter / debris.
Scan fuel rail pressure PID vs commanded -- CP4 failures show actual unable to reach commanded under load.
If debris confirmed, the job is: CP4 pump + both rails + all 8 injectors + lines flush ($8,000-$15,000).
Consider CP3 conversion kit as part of the rebuild to prevent recurrence.
