theresa,
Welcome to the forum! Honestly, the very first thing I'd probably do is pull a relay from one of the other non-essential systems and swap out the fuel pump relay - probably located on your '94 in the engine compartment against the firewall. If that doesn't fix it, you're probably going to need to begin a battery of tests - confirming that you do not have fuel pressure at the fuel rail. If there is no pressure, it could be the fuel pump itself (that one would be a pain), or the fuel pressure regulator, or a few other things. If it is getting fuel but simply won't fire, a common culprit is the throttle position sensor (TPS). Any or all of these things, given their age and use, can get flaky.
cheers!
Scott

Of course you understand that diagnosing a issue can only be as good as the information given. I'm not trying to be condescending, but you didn't say you put more gas in it. You said you ran out of gas, but then the car started again then stopped. Which could have used up every vapor in there. So did you add more gas? And if so how much? a Gallon? 1/2 Gallon? Did you use 93 and above fuel? Just asking.

Theresa, ribbing aside, sometimes when a car runs out of fuel even if no crud has been sucked into the fuel filters (which is highly likely it will have been), when you add more fuel and then try to start the car it can then crank until you kill the battery and still not start.
These modern fuel injected pressurized fuel system cars do not like running out of fuel.
Ex Mrs T was always running out, and when I did a roadside refuel I knew that I would have to jumper the car in order to get her car to crank fast enough and long enough to get the fuel up to the engine and back.
Read at least a full minute of cranking at full speed.
I hope that by now you are up and running, let us know how you faired.

Apparently in this age of textspeak, the ability to construct a coherent sentence is considered old hat.
u no wot i meen?
So it's up to us old pharts to attempt to decipher communications that use little if any of the accepted forms of punctuation, capitalization and structure that evolved to make the language understandable ... to make it "flow" and actually make sense.
Remember everybody, text often.
Do your share to contribute to the dumbing of America.

I'm not sure whether to take umbrage or not! Am I, in my mid-thirties, already to be considered an old Phart?! Or, are you simply living into the exalted category in these hallowed Jaguar Forums of "senior" member? (Although, truth be told, I did just this morning discover two gray hairs upon my face. Alas.)
lol.
