RE: Problem w/ start up...
 

Listen to Aussie,

he made the point I was going to make. You've got gas, now you just need compression and spark.
I'm with him, it's most likely battery, cables/wires. However there is the slight possibility it could be a mechanical issue.
There are good tests you can do to check your starting/charging/ignition systems. Information is readily available with a quick search through Google. You'll find web pages with instructions, diagrams, etc. The tests are easily performed with a simple DVM. If you stop by your local auto parts store they can test your battery for free.

Good luck,
