Huge boxster problem...

Apology accepted.

Things that make the car not start.

Fuel pump

You can pull the fuel pump relay and jumper it to run the pump. Search the forum for fuel pump and you'll run into it. If the pump runs scratch that off the list.

CPS - but usually fails hot and it seems you replaced it already.

Immobilizer under the drivers seat. Is it wet under the drivers seat? This is a whole new adventure if it is.

Top not working -I'm assuming the top motor is not running. Make sure the parking brake is on ( I made this mistake once). If the parking brake is pulled cycle it a couple of times to see if the top micro switch is failing.

Latch and unlatch the top a few times as well (another micro switch)

I don't understand what you mean by "the lights on so i cant get to the engine to fix it"

If it were me, I'd jumper the fuel pump next. Very common failure and easy test to run.
