Failure mode - Ford 3.5L EcoBoost Gasoline (F-150, Expedition, Transit, Raptor - 2011-present)

Low-pressure fuel delivery (in-tank pump / pressure faults)

Reliability tier: aggregated - verify before ordering, see /disclosure/

Symptoms

no-start / extended crank, more pronounced cold
power loss under load from fuel starvation
MIL with P0087-family codes

Compare with the other causes of the same sign on this engine: hard start, long crank or no-start (5 causes) · loss of power, limp mode or derate (5 causes)

Root cause

In-tank pump and delivery-side faults (pump wear, pressure regulation, wiring) starve the HPFP; Ford also issued a Gen1 cold-weather no-start/hard-start bulletin below -15C for MY2011-2014 trucks.

Diagnosis

log low-side fuel pressure at rail inlet, cold and hot
verify pump power/ground and the filter state before pump replacement
apply the cold-weather bulletin triage below -15C before parts

Fixes

in-tank pump module / filter service; wiring correction where the fault is electrical ()
