The motor worked before replacing the timer??? If so, I'd say you may have a broken wire or have gotten a bad timer or the wrong timer. I can advise on making a test cable from an extension cord to test the motor if you have the tools and ability to do so? You'll need to strip the cable/wires and install quick-disconnect terminals. I may have the wiring diagram but I need a clear photo of the electronic control board to be sure it's the right one. There should have been a tech sheet with wiring diagram somewhere inside the control panel.
