Check to see if the fuel pump runs for a few seconds when you first turn the key to the "run" position. You should be able to hear it if you put your ear to the gas cap while someone turns the key. It will run for 3 or 4 seconds and then stop.
Check for spark. Easiest way it to hook a timing light to any wire and turn the engine over. There are many reasons for no spark. Most common being the coil, sensors, MAF etc.
If the fuel pump isn't running. Check fuses, wires, and finally... change the fuel pump if all else fails. You would be well advised to find one at an auto wrecker if you can. They are expensive.

Check the dash once you turn the key to the run position the passlock runs a security check using a set resistance value through the chip in the key. If the security light begins to flash the reading it received was incorrect or it didn't get a reading at all. You can try reseting the value it is looking for by turning the key to start then releasing it. After 10 minutes turn it off then cycle it start again leaving it in on for 10 minutes then back to off then one more time. After the third cycle has completed for a total of 30 minutes. You should be able to turn the key on and start the vehicle. If the light continues to flash their is a problem with the chip in the key or the connections within the ignition its self. Both are common but a Pass Lock Relearn as described above will usually adapt to the poor connection values. Hope this helps.

if you can put fuel in throttle body and it runs. then it is not getting any fuel. check your fuel pump fuse and the relay, if ok, then you may have a bad fuel pump or a plugged up fuel filter. check filter and fuses first. good-day !!

Is it making any noise at all when you push the button? If it is making noises, then you probably have a broken window regulator. If is is not doing ANYTHING, then you probably have a bad switch or a bad window motor.
You can find out which it is by popping the switch out of the door and checking for power and ground at the switch connector. (back-probe the connector with it still connected to the switch)
The circuits to the driver's door motor are Connector C2 - DARK BLUE Pin "A" and BROWN Pin "E" (C2 is the Long, 8-pin connector)
BOTH of these wires shouldbe GROUND when the switch is in the NEUTRAL position. Then with the ignition switch ON, the BROWN wire will switch from GROUND to POWER when the switch is pushed "DOWN". The DARK BLUE wire will do the same when the switch is pushed "UP".
If these are not doing as described, replace the switch. If they are switching properly, then you need to check for power and ground at the motor connector. - chances are it needs a motor, but you need to check the power and ground just to make sure you do not have a broken wire between the switch and the motor.
