Question about 2003 Chevrolet Tahoe
I did spray a little ether in the air box(I know not a good ldea) and the engine ran until it burned off the ether.
It wouldn't hurt to check fuel pressure with a fuel pressure gauge. you should see somewhere around 48 - 55 psi. the test port is on the fuel rail about in the middle of the rail and on the drivers side.
If the fuel fuel pressure is low it wouldn't hurt to make sure there is power to the fuel pump before condemning it. Power is supplied to the pump by the larger of the two grey wires.
The fuel pump is located in the fuel tank and the fuel tank will need to be dropped from the vehicle in order to service the fuel pump.
If you decide to replace the fuel pump get an a/c delco or a delphi pump. These are the best two option for your vehicle. Do not get an airtex brand. They are not reliable pumps although they are cheap.
Let me know if you have any questions and thank you for using fixya.com!

Testimonial: "thank you so much i will try that.can u tell me where it is"
It probable is out of gas these GM vehicles are famous for bad fuel sending units.So if i were you i would replace the whole fuel pump assembly the sending unit comes with it,that you won't have to pull the fuel tank again because of fuel pressure problems later on.
