Fred,
There is a relay on top of the pump. On my 02’ Marquis, the pump is located under the entryway steps. I assume on the 02’ PT, it is located in the same place. Check to see if the trigger wire on the hydraulic pump solenoid is getting power when the slide switch or the leveling sequence is activated. If the trigger wire on the hydraulic pump solenoid is getting power, then the solenoid is bad. At this point, you can jump the two larger terminals on the solenoid, if pump works, then solenoid is bad. If pump does not work, then pump is bad. Also, make sure all terminals are tight. Be careful when tightening big terminals or jumping solenoid, one side is hot and will arc if grounded. Hope this helps
