make sure car has 1/4 to 1/2 a tank, then check fuel pressure. I believe your car has a valve on its fuel rail where the fuel injectors attach. It looks similar to tire valve. You can get a fuel pressure gauge for like $20 at advance auto and attach it to the valve i mentioned and turn key to run position then off. Do that 3 times and check gauge. Not sure actually what numbers your car needs but id say 40-60psi is normal on most cars. then start car and see what kind of pressure you have. If you have no pressure, id say bad fuse or plugged fuel filter, fuel pump relay, or pump.

If you don't have at least 1/4 gas in the tank on the regular basis you can wear out your fuel pump. In extreme heat and cold you need fuel to keep the fuel pump working cool at those times. If you're warming it up chances are it's cold out and you probably killed your fuel pump, change the filter and have the fuel pump tested.
