try searching the list again. There was a recent thread that started last december and went around for a couple months. Turned out to be the fuel pump. But I can't recommend throwing parts at it. The thread would be useful because there's lots of good advice for diagnosing the problem. Literally could be dozens and dozens of things.

I don't the think the EHA or the water sensor is where I'd start. You could attach a timing light to the plug wires to ensure you have spark. Then I'd shoot some ether into the throttle body while trying to start it up (depress the gas pedal a little too). If it sounds like there's combustion then you know you've got a fuel system problem. Next steps would be to verify the operation of the fuel pump, cold start valve, and the idle control valve. fuel pump is pretty easy - try to start the engine and return the key to the "on" position - if you hear a humming from the back of the car that continues for a second or two then you know the main pump is functional.

Good luck
