There are not many things that cause a no start with a cranking engine.
Fuel: pump or relay.
Spark: bad RPM sensor, ignition relay, throttle sensor, MAF.
Temp sensor: signalling a hot engine when it actually is cold.
I am sure there are few others, but this comes to mind right away.
Since it is that time of the year, "lawn mower syndrome". A condition that developes when at colder temperatures, the engine is started and stopped after just a few seconds, as to move the car out of the garage to get your lawn mower.
Not sure what the cause is but the engine loses some compression and will not start, it seems some, or all the valves are stuck in a slightly open position and will not allow sufficient compression to start up. The only cure is to have a strong battery and continue to crank about 2-3 minutes. With your foot firmly on the gas pedal to the floor (this cuts fuel to injectors). This allows the engine to recover enough compression to want to start. It comes back one cylinder at a time. It has happened to me about three times before I figured it out years ago. Then a search for lawn mower syndrome showed it happens a lot.
Let us know what it turns out to be.
