I am trying to simulate a buck boost converter with a pmos and I cant get an output voltage. This circuit was originally with an nmos and worked well. I changed it to pmos, switched the source and drain, inverted the pulse and grounded the source. The circuit currently has an ideal mosfet so VGs should be fine. Any help is appreciated.
I have attached an image of the circuit and the asc file.

 

Welcome to AAC!
Generic MOSFETS rarely do what you expect. Select one of the models instead.

 

As Alec noted, never use a generic semiconductor in LTspice.
They are not necessarily "ideal".
In this case the generic MOSFET model doesn't seem to work at all.

With a P-MOSFET from the library, the output magnitude is over -9V (below).
