So I can hear the sprayer pumping, but my front nozzles don't spray just dribble out, my rear sprayer works fine. I didn't see any leakage when i popped the hood. Don't see any leaks in the hoses, though the cap to the canister is cracked open.

 

welcome to the forum you might want to blow out the spray nozzles backwards to make sure they are clear.

 

I agree,sometimes sludge and trash can clog the lines.

 

Wax will clog the sprayer nozzles.. use something small like a strand of stiff wire or maybe a needle..
