Make sure battery has a full charge and battery connections all good. Check fusible links where applicable. Any component that doesn't work and is fuse protected, not only check the fuse, check the fuse circuit for voltage, use a test lite.
The wiring diagram is for starter circuit, you can see the fuses. Any testing for starter motor, make sure tranny is in park or neutral and parking brake is set. It is possible to jump crank relay to see if starter motor will crank, but, that doesn't mean it will start. Make sure vehicle can't move.

The level sensor is in the fuel tank. If you replaced the pump, make sure the sensor wire is connected at the tank.

It's the anti-theft system . (SECURITY ) Keeps vehicle from being stolen !
Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II?® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
Your best bet would be have it towed to a qualified repair shop !

Try to check the ignition switch that is on the steering column inside the car and under the dashboard.
Do not buy a new one, first see if the ignition switch is getting any "juice", and then if it is sending any "juice" to the starter when the key switch is turned.
The ignition switch is not the key switch, but it is connected to the key switch with a push rod.
The ignition switch is down in the area of your shins.
God bless your efforts.

Usually the lense pops off and the bulb comes out.
It should be described in your owners manual.

If the leak is not too large, a tube of aluma seal from an auto parts store may do it. Its a powder that you add to the radiator.

as good as any ,like mustard or egg white ,better fitting a new radiator but as a get you home measure this will work

If the radiator is cracked, replace it. Radiators run at high pressure, high temperature. Any repairs would be temporary.
