The answer to your question is in the faq and I'm sure if you do a search you will come up with the answer multiple times.

To answer the question again though, 3 even pulses above 100psi is good. If they are at 90psi then the motor will still run but it is on its last legs. Below 90, or if all the pulses aren't even, means you have a problem.
