Inverter and running engine?

OK,OK

Been here before long time ago, my car is about to be taken off the road for a few months while i install everything but just one question, if powering a PC say (non-epia) what are the chances of it running with the engine off from a power inverter? only i seem to remember someone local to me having this sort of problem, bit of a pain if your waiting to pick up the missus and to listen to some music you need the engine running all the time

It will run fine, it just won't survive cranking the engine, and will slowly drain the battery The only difference is the current is coming from the alternator(+/-14.5V) when the car is on, and the battery(12V) when off.

Depends on how long you plan on waiting and how good of a charge you battery holds.

Simple answer is yes.

I have no problem running my CarPC at least 1 hour off the stock battery when the engine is off and I can still start the car after that. Since you are using an inverter I highly suggest you look into the so called tank circuit so your inverter will survive the crank
