So many things.....

Does it have enough gas to cover the fuel pump pickup? One gallon might not do it.

Check under the hood for wiring damage from mice. My mom's car has been damaged many times from mice.

Two things to verify (assuming we don't have any netruel safety switch issues).
First do you have spark at plugs.
Second, get a pressure gauge to verify you have fuel at fuel rail on engine. I believe it's around 30psi.
Also somewhat common is the "crank position" sensor gone bad. That generates a pulse to fire fuel injectors.

I've run into almost the same thing on a Dodge. Sat for a very long time then was cranked. Ran fine but wasn't really driven or any fresh fuel added. Next day no start.
In that case it turned out the electric fuel was gunked up from sitting so long. After getting warm a bit then it seized up. Conjecture really, but I managed to disassemble the pump and clean it up to fix the car.
The first thing to do to see if something like that happened is to check for fuel pressure.
Another victim died overnight from what appeared to be the same thing, but wasn't. Car ran and drove and didn't start the next day. Turned out it was parked on an ant pile. For some reason fire ants decided to bed down inside the fuel pump relay. Cleaned out the bodies and the car started.
Could be all sorts of things. Check the simple stuff first. Good luck.

is the fuel pump primeing?

good ideas thanks....you know i'll never understand that when you have a car that will start right up and run good,smooth and quite and let it run for 10 min or so and you turn it off, it doesn't quit on you and then it won't start and run again.....these never cars are a pain! but thanks guys..

Things necessary for an engine to start:

1) fuel/ pressure
2) healthy spark
3) compression
4) clear exhaust
5) correctly timed engine

1st step see if you hear the fuel pump come on when the key is turned on, If it does not sometimes you can kick the fuel tank to get it to work (this is for fuel injected cars with fuel pump in the tank btw) If that gets it working you will need a new pump

If it works great, if nothing makes noise, on some cars you can disconnect the intake hose and spray carb cleaner into the hose, this will act as a subsitute for gasoline. If the car fires you have a fuel delivery problem (pump/filter) you should check for power back to the pump before replacing.

If you have fuel, proceed to begin checking for a good healthy spark. if you have no spark work from the plug wires back.

since your car was recently a running car with no problems until it was parked I believe you have either a fuel or spark problem, I would concentrate on these two area first, my guess is its a fuel problem
