HI there,

If you spray carb cleaner or starting fluid directly into the throttle and crank the car will it run for a few seconds?

No I tried that?

So, it's possible or likely the car has lost power to the fuel pump, injector pulse and spark. This would usually indicate an issue with a crank position sensor or a cam position sensor. The fuel pump will only see power for about 2 seconds if the computer doesn't see any engine rpm. If possible I wold scan for codes or use a code reader. Typically this kind of problem is a result of one of those sensors failing and not sending a signal to the computer.. If you haven't, you should get a code reader and see if there is anything in the computer.
