I got a customer that replaced the supply fuel pump and we are getting fuel to the injection pump but will not start cranks fine. Kubota says it a 1g77550102 I not worked on much kubota i not sure if it has a suction control valve or if the injection pump easy to replace

What were the symptoms that prompted him to replace the lift pump? This is a mechanical pump, no suction control.
First, resist the urge to use starting fluid. Hopefully, you haven't already. There is a manual plunger on top of the injection pump to prime it, follow the procedure below for bleeding the fuel system.
There is a fuel solenoid on the injection pump that must be energized for the engine to run. This solenoid has two coils, thus two wires, and the case is ground. Both coils are energized together, but the pull-in coil has an internal switch which deenergizes it when the plunger pulls in. Make sure you have 12 volts at the connector when the keyswitch is on. If so, remove the solenoid, watch that the plunger pulls in when you turn the key on. If not, you probably have a bad solenoid.
I think this tractor will run with the solenoid pulled out, but it won't stop, so you'll need to stick the solenoid back in to shut it off.
It just died and was under power on him when he was running it. I've been able to go over there and prime the system, but it will not get fuel pass the injection pump. I have ordered a new injection pump. Because I thought it was that, and I will change it out tomorrow and check the fuel solenoid are this pump easy to replace

Did he reinstall the shim under the pump?
If your not getting fuel out of the Injection pump then you have an issue with the Fuel solenoid.
