Check the exhaust compression. Remove the O2 sensors before the cataylic converts and see if it improves. If it does that means your cats are cloged and need to be replaced.

Check/Change Fuel Filter(s), PVC Valve & Emission Hoses
Gas that sits too long won't fire easily that's why we have to add winterize to our lawn mowers!
Try filling the tank with some high grade fuel cleaner additive. This stuff is like rocket fuel (about $10).
Also add a can of dry gas as you may have a lot of water and water vapor in your system!
Get a couple more cans of starter fluid too. (I always needed at least two to get my diesel running for summer)
Keep spraying and starting (It always took me at least a full can sometimes 2)
When it starts keep the gas pedal down and rev high for a good 5-10 minutes then see if it will idle.
If it still stumbles and falls consider adding another can of fuel system cleaner and/or dry gas.
Don't drain the tank as this usually just makes it worse by letting the bottom sludge stir up.
Never let your gas tank get too low as this will foul up your fuel system and always add fuel cleaner after every oil change (a must for fuel injection and cat. converter care)
PLEASE RATE THIS!

Turn the key to the ON position without starting the engine. You should hear the fuel pump running for 5 seconds if working. This primes the gas to the injectors when doing this. If not heard running check the oil pressure switch for the 12 volts needed to run the fuel pump starts there on that harness. When the engine starts and the oil pressure reaches the normal pressure the computer shuts off that circuit and turns on the fuel pump relay to run the pump. The relay stays on till you shut the engine off

ummm that could very well be the fuel pump... you want to check the fuel pump fuse and also the solenoid thay do go out but most likely the fuel pump has gone out one way to check and see if its the fuel problem is to spray some carb cleaner in the air in take and try to start if it dos and dies that means your not getting fuel delivery also test your pump delivery pressure....the fuel pump is located in side the fuel tank...

OK, let me help you with the diagnosis without having to do the "Fred Flintstone beat on the fuel tank" thing.
All you really need is a 12 volt test light and a LONG jumper wire.
Since you already know where the inertia switch is (red button in the trunk), this should be very simple for you.Connect one end of the jumper wire SECURELY to the NEGATIVE battery post. Then string the wire back to the trunk (we want to make absolutely certain that we have a known-good ground for our test lamp).
Then connect the cable end of the test lamp to the wire.
Disconnect the connector at the inertia switch. Using the probe end of the test lamp, probe Pin #1 PINK/BLACK (unfortunately, on your vehicle, BOTH wires are PINK/BLACK, so you know which pin to probe, pin #3 is the one that is not used - pin 31 is the one on the other end of the connector.)
Turn the ignition switch to the ON position. Your test lamp should light up for approximately 2 - 3 seconds then go back out. If it does, then you powertrain control relay, your fuel pump relay, the fuses for each of them and the PCM are functioning properly. If it does not light, let me know and we will go on to find out WHY.
If all of this is working, you most likely need a fuel pump. It IS possible that you could have a bad connection between the inertia switch and the fuel pump unit, but it is not very likely and you will have to pull the fuel tank to find out ....So, you may as well put a new fuel pump in if you are going to have to go through all of this anyway.
