Started tractor!!! Two of the injector valves were stuck. Freed them by carefully prying up and down. Tractor started instantly. Thanks for all of the great info. Most of my antique’s are gas engines. Will need to learn more about diesels.

Again Thanks

Many times they bleed easy, but some times they don't go until you open the bleeder valves like mog was saying.

Not knowing your level of Cat knowledge you do have the compression release in the run position after warming the diesel up and then turning on the fuel? If there are questions about the right procedure check out Sasquatch's you tube video on the subject.

My personal thought is there will be many more problems with sticking injector pumps from setting going forward with modern fuel with less lubricating than older fuel. The last old Cat I drug home and have run had diesel from the early 90's or older ran fine except for the rust in the tank from not being full.

I had a similar problem on a 1953 D2 5U. I replaced the injectors and it started right up.
