Hi

It could be many things, so start with the basics:

Check to see if you hear the gas pump buzz when you first turn on the key
where all the lights are on, but the car is not started. You'll hear a
slight buzz coming from what appear to be the trunk and after two seconds a
click from under your dash. Not hearing the buzz and/or the click  might
suggest the fuel pump or main relay -- especially the relay is notorious for
messing up like that.
Also, usually when you start the car (without it actually starting) you will
smell the gas under the hood if gas is getting to the engine.

If you know you are getting gas, check for spark. If you don't know how to
check, get a simple tool from Autozone/Pepboys to plug instead of one
sparkplug and start the car to observe the spark while someone starts the
car.

Knowing these basics will help you find the problem - just post your result
back here. Plenty of guys (gals too, come to think of it :) know where to
take it from there and suggest other things to try.

====================

If it doesn't run the fuel pump when you (quietly) switch the key to
position II, smack the dash to the left side of the steering wheel. If
you hear the pump run for three seconds, try starting it. It will start.

troubles.

1) Got fuel? 2) Got spark?

Fried ECU requires investigation then installation. For example, open
diode in main relay can destroy ECU's driver circuit, thus no fuel
days later. Diagnose now, or risk another dead ECU.
