AnswerJuan,
I'd like to have a quick answer that would work for all those cars that end up sitting for some time. But the only obvious area would be varnish/crud in the fuel lines. Since you've obviously got plenty of fuel, that's not a likely cause (although I'm not ready to rule 'fuel' out completely). I'll give you a list of some items to check and then you'll be able to rule them out. Here we go:
1. Battery discharged, starter rotating, but too slowly.
2. Battery terminals loose or corroded.
3. Leaking fuel injectors, clogged fuel injectors, faulty fuel pump or regulator (not the right pressure).
4. Ignition components damp or damaged.
5. Worn, faulty or incorrectly gapped plugs.
6. Broken, loose, or disconnected wiring in the starting circuit.
7. Broken, loose, or disconnected wiring at the ignition coil, or faulty coil.
Since there are several wiring possibilities, I'd suggest, if you haven't already, going through every wire/connection listed above...disconnecting, examining, and cleaning, etc., so you know you've got these bases covered.
I hope you find the glitch quickly, so you can get that Porsche back on the rode where she belongs.
