If you compressor starts the water pump should start soon after. Then you should get heat or cooling. If it heats or cools but not well in either mode it is probably a low gas charge. This is easy to rectify by having an HVAC guy access the cocloed ports to add the appropriate gas.
If it will not start at all check the fuse, the ground and the wires from the control pad at the unit's printed circuit board for good connection and ground.
Check the intake and blower vents for obstructions.
If all of that is good try tapping (gently) the compressor with a rubber mallet or reversing the heat and cool cycles a few times to see if the reversing valve shakes things up a bit. If that starts the compressor it may have been partially seized.
After a few minutes the water supply pump should start. If it doesn't check the water pump strainer for weed clogging or loss of prime.
There are good trouble shooting mini manuals that have been posted on here. I think we had a recent discussion of this last summer. I know I posted some manual pages.
