Yep i've had this happen to my dexta , and you gone back to front about this the larst thing you should do is messing around with fuel pump. If the tractor looses power and stops nearly always fuel starvation start with fuel tap is diesel coming out if not rubbish in the tank if it dose go down the line next stop fuel tape to fuel filter extra . You can check for air by bleeding the pump then the injectors
Samuel High it runs again but have fuel leaks and it idles real high but I think that’s because of sucking in air through the leaks. My bigger problem in it has very low power when in gear, won’t even go up a hill, thanks for your response though 👍
Don't spend to much time and money on tractor till you get fuel going to the injectors and adjust and clean them. If the motor runs some what on starter spray I would say it's a fuel problem . There's a free manual on the Internet that has a lot of imfo. gm
