Got a case 580 se backhoe with a 4 cylinder Cummins. The injector pump looks as though it has been rebuilt at some point. I have owned this machine since November of 21. From the time I got it home, it has had a starting issue.
If it sits for a day, a week, a month, it will start right up and run as long as you want to. When you shut it off, it will not start again unless it sits for a good while or you open the fuel bleed screw and release the pressure. It will then start up and go until you turn it off.
I have replaced the fuel shut solenoid (twice, just to make sure), checked the voltage to the solenoid when trying to start it, made sure the return to the tank is not clogged.
This is the first piece of equipment like this I have owned, so looking for help as to what may be the problem.
I will try to attach a picture of the tag on the pump.
