Can I fix my 400w fog machine?

I dont know the mechanics fog machines,so heres a problem u probably already heard,or know about.. I have a cheapy  400 watts Gemmy (about 6 or 7  years old). I pulled it out of the attic thinking it needed a good cleanout before halloween. I mixed up a 50/50 bottle of white vinegar and distilled water - turned it on and got one good 20-30 second burst from it.On 2nd burst a little leftover came out then nothing.Still heats up hot and I can hear pump humming when i trigger the remote. Next, I empty the tank and tried straight fog juice and still nothing.I emptied the tank  and cleaned the tank filter tried it all again and still nothing...Could it be somewhere in the solid copper tubing from the pump to the heater and how do I clean that?   I did however store it without fog juice in it..(empty),could that a cause of problum ?  Please help.. TKS.

It could be the pump has failed. It may still make noise but may not be bale to push anything.

TKS.for the reply..
So you dont think somthing might be clogging the copper tube? But,if its the pump,it woulnt be worth fixing-would it?
