And you're sure you have power to the shut off solenoid stud on top of the injection pump, right?

Does the tractor have thermistor to control the injection pump solenoid?
If so check it out.

That cold start thermistor has probably shorted. You probably have a blown fuse because of it. There's a wire that is attached to the shutoff solenoid power stud on the pump that can be removed and abandoned. That will clear the short. Replace the fuse and you should be good.
I’m a novice at this I’ll check could you possibly give me the proper sequence of the proper way to check this and if I don’t what would be the next step
Thanks you

Under the inj pump is a set of wires.. follow them up until u find the plug-in & unplug it..
Next, find the blown fuse in the fuse box and replace it..
It’ll start now.

I'm not sure the plug under the pump will stop the problem. The connector at the temp sensor is probably first in line after the fuse, so if that's still in play the next fuse will blow too.
Start with test light at the stud on top of the pump. One should get power, the other has a ground strap. If you have power there, then all the talk about fuses, sensors, this and that, is not part of your problem. If there is no power with the key on, then go from there. Fuses, etc. I would start by disconnecting the temp sensor if there is a fuse problem. Fact is, I generally disconnect them anyway. That system is nothing but trouble.

There is no plug. At least if it's like my 5310 was. There is a stud on the injector pump with 2 wires. One wire come from the relay and the other goes to the thermistor. The wire going to the thermistor leaves and goes toward the front of the tractor. Take that wire off. Leave it off. Tape it up. Check for blown fuses. You should have one. Replace the fuse and you should be good.

If you do not find a blown fuse put in a new thermistor. It’s a ten dollar item.
It gives more amperage to open the solenoid and then reduces amperage to keep it open.

I have no blown fuses
yes
