firing pin won't engage

[aceman]

I need help with my savage 64f .22 semi-auto which is still new,
but after disassembling for cleaning per the manual, I then put
it back together in reverse, and now when I pull the trigger it
goes click but no fire or mark on the bullet! The first time I did this last year, it worked fine, but I've repeated the steps several times, and still "click" and no fire. According to the manual, you're suppose to pull the trigger to "disengage" the hammer from the sear, and I may have not done this properly.
I don't want to take weeks sending this back to savage, is there
anyone that has some simply ideas to fix this "simple" screwup?

Thanks, Earl.
