So I just got this m35a2. I got it running bit now it dies and wont start. Seems to be a fuel issue. I have fuel pressure and plenty of fuel getting to the injection pump, but nothing coming out of it. I pulled the hydraulic head and inspected it, seems to be fine. The clip and button are in place, the bowtie key is there and in good shape. I put it back on, pulled the top plug and I can feel the plunger moving up and down and the hydride head is getting plenty of fuel to it, but still hardly anything coming out of the injector holes. Is there anything I could be missing here? Any more ideas?
