I have a submersible pump I had the tank replaced proffessionally and the pressure switch!! I woke up this morning and no water went to check pump points were burnt, so I bought a new pressure switch wired it the same as old switch and nothing works!! What do I do?

You're not going to like my answer.
If there are no shorts in the wires to the pump It sounds to me that the motor windings have shorted out.
This means pulling then pump and locating the short. Good luck, Tom
