Manual "run 1 zone" or "run all zones now" only works occasionally.

We are fairly new to the irrigation system, having inherited the original pump which is about 13-15 years old. We replaced the controller (Rainbird) last summer. Our system uses ground water. We have had difficulty with our pump kicking on if we want to manually test a sprinkler head or water 1 zone randomly. Sometimes it kicks on - other times you hear it click as though it's going to start and then momentarily it clicks and goes off. The timer still ticks down time. What's odd - is that sometimes it will come on, sometimes on the 3rd or 4th try it will come on like it should. And it seems to come on routinely when it is programmed to kick on. Have checked the primer plug and it is full of water. Any ideas?
