Try start the car again when it is completely dry, if it starts the rain may be short circuiting something on the loom in the engine bay.

If it still wont start,

will it turn over? (car tries to start)
- If it wont turn over the battery would be dead

- If it turns over but wont burst into life then we can go from there ^_^

    Battery was completely charged. Turns over! Acts like no fuel or spark.

    Ok, To check the spark disconnect the spark plug leads from the spark plugs (be very careful to remember where they went) disconnect 1 spark plug and connect it to a lead. Try to turn the car over where you can see the spark plug and if it sparks then the car has spark. Do this with all leads. If it isn't a spark problem I will go more in depth with a fuel diagnose after

    I believe camshaft sensor is problem.... Had spark heard fuel pump running but couldn't check pressure. Thanks for your expertise!

Code scan for faulty crankshaft sensor or camshaft position sensor. listen for fuel pump running turn ignition should hear fuel pump running for 3 seconds.if hear no fuel pump running check fuel pump fuse and relay.if fuel pump running check fuel pressure should be 41 - 47 psi. with new fuel filter.if fuel system okay.more likely problem could be ignition system.check ignition fuse.could have bad spark plugs and wires if engine wont crank in wet damp conditions.but code scan before buying new parts.

    you could also look at the wiring harness located under ther vehicle just behind the drivers seat. This connector will get corroded and rot away the wires. will cause many problems including no start. there are wires that go directly to your fuel pump and sending unit.

My car won't turn on it was working fine last

Just because you charged the battery it doesn't mean it is any good. Modern sealed batteries fail; just as you described, fine one moment and then nothing, they go open internally.
