Im have proublems geting my injector pump to work , It checked out Ok at the shop, and I had new seals put in but now no Pump, and no ones got any info on this tractor
Did you bleed the system? Injector pumps can not pump air much less self prime.
Standard proceedure is to crack lines (or open valves) starting from filter all the way thru to the pump and I even crack the lines at each injecter 'till it spurts.
My current trick is to clamp shut the line coming out of my filter whenever I change filter elements thus saving all the bleeding process.
If you don't bleed, you can crank away 'til the battery is drained or the starter burns up.
