i just came back from the dealer they got the tank open for me and said that the motor wasnt giving off air to the hoses, so i will need a new pump....i placed a order for one at shokan for $165

 

Had the exact same problem...pump would run, but no locky. I needed a new pump as well.

My pump shut itself off after 30 seconds or so, so no worries about draining the battery. Mine was (thankfully) still covered under extended warrenty...it qualifies as "equipment failure."

Sux man...you're not the first poster I've seen with this problem, I guess it's somewhat common.
