conditions under which it quit working?
any repairs done lately?
which engine 3L or 4L?
any codes?
got spark to all plugs? use one of those clamp on spark plug wire testers
is spark bright blue and snap?
any backfiring?
use regular gas only. 89 or 92 octane has additives which decrease vaporization and do not start as well.
the winter blend regular has additives for better cold weather starting.
using starter fluid with ether is not healthy for long engine life. breaks the heads in 4L especially.

Started right up today. I think its the fuel pump, how could i check? The fuel gage is close to E and so is my wallet. It was parked in my driveway with the rear end obout 3 inches lower than the front end...would that be a fuel pump?

How to check fuel pump: when put your keys in your ignition, and turn it forward so all your accessories are on and as are you dash lights. you should hear a mechanical hum. that hum is the fuel pump presurising the lines. if you don't hear a hum, you fuel pump isn't working.

I would add some fuel, running down to E is hard on the fuel pump because the fuel actually cools the pump. I know gas is expensive, (in relative terms by dad says,) but it is still cheaper to put $10 of gas in than an $80 fuel pump and $200 labor (if you pay someone to do it.)

Fill 'er up!
Not only the fuel pump problem , if you run the engine that low on fuel it may temporarily affect the fuel strategy. Some of these engines have adaptive strategy, which will try to correct for lean mixture, simple solution, dont run the tank into the red sector. Besides that condensation which is water & other junk will be sucked into the fuel filter & lines especially bad in the winter.

Periodic fuel filter replacement can extend fuel pump life. An occluded filter makes the pump work harder and cool itself less due to reduced flow.

But water in the fuel lines is even worse in the winter as it freezes & ice is one of the better plugger uppers; as it expands as it cools! & if temp fluctuations are suitable, condensation builds up much more quickly with low fuel level in the tank. I run mine down to no lower than 1/4 on the gauge. Seems to do the trick !
