Van died on the side of the road, no power, lots of black smoke before she died. Towed to diesel shop and they said it needed a new injector pump. Have now installed the new injector pump and it still will not start? Injectors are all getting fuel, fuel bowl is full, glow plugs are all working. Turns over and over but does not try to fire? I poured some fuel down in the intake, nothing. I got a magic can of either(ouch) and tried that, no luck! Has lots of compression. I had it scanned for any codes, no codes showed up? Any thoughts?
