Is it a deep well jet or a shallow well jet? A shallow well jet has one pipe to the well; a deep well jet has two pipes to the well.
That number you gave could be a motor number. I could not match it to a pump. Is there a number on the pump body?
What kind of well is it? Drilled, dug, driven? What size casing? How deep?
Do you have a pressure tank or are you pumping directly to the irrigations system?
Can you check the depth to water in the well?
Do you have a pressure gauge on the pump? If not, you should get one. No pressure gauge is like flying blind.
The jet could be plugged. If it is a shallow well jet you may be able to clean it by removing the inlet pipe and looking inside to clean it out with a wire probe. If the inlet is not on the centerline, then there may be a plug on the centerline to provide access. If it is a conertible jet, then the jet is on the outside, bolted on.
If there is a failure in the suction pipe it could lose prime. Try priming the pump.
You could test a shallow well pump by removing the suction pipe and putting a pipe or large hose in a tub of water to see if the pump will pump water. Put the discharge back into the tub so you can get a few minutes of pumping. Then see if it will pump through the irrigation system.
