2004 Hyundai Sonata won't start or starts hard in wet weather. Any ideas? Battery is good, engine cranks, but won't catch. The car is fine in dry weather. Mist or prolonged heavy rain seem to cause the worst problems.

Based on your description, it seems like the car's battery may have been affected by the cold weather. Cold temperatures can cause a battery to lose its charge and reduce its capacity to start the engine. When the temperature rose, the chemical reactions in the battery sped up allowing the battery to regain some of its charge.
However, there could be other reasons why your car wouldn't start. For instance, it could be due to a faulty starter or solenoid Determining that would likely take a visit to the dealership.
There are a few ideas here. The car shouldn't start in neutral, it should only start in Park and with foot on the brake. The are a number of sensors, switches and modules that make this happen. Take it to the dealership.
94-95 B Bodies have a On Board Diagnostic Built in the AC System! Try holding the AC "OFF" and "TEMP^" buttons at the same time until the screen looks funny with all the lights on! the scroll with the temp up and down button till u see 00 and hit the button that says "MIDDLE" to enter! If done right, i will start displaying any stored dtc codes. tehn let me know what code it shows!
I suggest that you look for secondary voltage leaks from the ignition system. Moisture causes dirt to become a pathway for this spark voltage. Look inside all wire connections, for any corrosion. A scope can test this, but typically a home does not have a scope...
it may be a weak battery if when jumping it the engine didnt spin fast,but i belive the first time the battery was weak and trying to start may have flooded it with the cold weather, have the battery tested and replace it if not good then try holding the gas pedal down to floor like the older cars and hold it until motor gets going then slowly let up as rpms rise, you may have to crank a while.
check to see if getting spark or fuel if no spark could be crank sensor or cam sensor have to check voltage out of wiring harness if low voltage ecm bad. Pull both coil wires off coil and have someone turn ignition no spark probably ecm. For fuel check number one plug see if wet and also listen when you turn key for fuel pump. If driving it just died on ya and battery went dead like know and you tried jumping or replacing battery.Still would not start ecm bad.
