You need to check fuel pressure. Can you turn the key on and hear the pump running? Did you run it out of gas? The fuel pump is gas cooled, running it low exposes the pump and can kill them pretty easy.

I'm pretty sure that your best bet would be to take the car to a professional. This is the sort of problem that is a million times easier to pinpoint when you have all of the expensive diagnostic equipment that every good shop has.

If you want to save money and you are reasonably competent working on an engine, just pay the shop for the diagnostic fee (typically $50 or less; I'm not sure what it will be in Aruba), and have them tell you what's wrong. Then you can do the actual repairs yourself.

Lots of guesses could be made, but replacing things on guesses would cost you more money than having it diagnosed. Also please read the abuse of TTT sticky.
