Diagnosis & fix steps
Fuel Rail Pressure Too Low.
LOGIC: The high-pressure pump cannot maintain the 300+ bar required for idling.
Red Seal field insights
Check the Fuel Quantity Control Valve on the rail. Also, Sprinter fuel filters are "pressure-sensitive." If you used a cheap aftermarket filter, it might not be flowing enough volume to satisfy the high-pressure pump. Always use OEM fuel filters.
