I have a 6080 AC that is getting fuel to the injection pump but will not start. I have power to the fuel shutoff solenoid when the switch is on but I don't hear it click like it normally does and I am getting no fuel to the injection nozzles. Does anyone have any suggestions on how to fix this. It was starting just fine this morning but when I went back to start it would not start.

If it isn't clicking and you're certain you have good power to it, the shut-off solenoid is bad. You might try and run a new wire from the battery post on the starter hot cable direct to the injection pump and see what happens. Just because you may light a test light doesn't mean it is a good 12 volt signal under load.
