Diesel Sprinter Injection Pump. We misdiagnosed, put the part on and had the same problem, turned out to be a glow plug roblem. Meanwhile, stuck with a new (only used for a few minutes) injection pump. DTech DT6420700301R, fits multiple years of Soprinters as well as some Mercedes Diesel SUVs like the R320. Check with your parts sources for fitment. I will pay shipping to you, you ship back for core refund. I paid $595 plus $275 core for this. Will sell for $495 plus refundable core.
