Outdoor propane grill - won't light

[syswizard]

I fear that water has gotten into the tubes running from the tank.
Previously, it was very reliable.
I there anyway to flush out the water ?
Part of this is my problem...I left it outside with no cover.
A year ago I had it covered with a cheap cover from Home Deport....which then got torn apart in some violent winds.
Another Chinese disaster.....cheap, cheap, cheap.

Don't want to sound like a smart a... but does the gas flow? If the sparker is not working I have seen some with a battery so that might be a place to look.
