Leave the lines loose for a while at the injectors while cranking. You may still have air pockets in the line and it doesn't push through.Yes I have fuel at the injector & the filter is full it always cranks on the first turnover
You might have some crud in your fuel lines . . . if you have a string trimmer take a few feet of the line and run it threw your fuel lines to clean the crud out.Need some help I have a 1971 MF 135 diesel I changed the fuel filter and now I can’t get it primed back to start up .
