Hello, my name is ***** ***** I am going to assist you with this.
When you press and hold the STOP/PRIME button, do you hear the fuel pump running?
If so, and you have tried using a stand alone can, then the pump is bad.
If you do not hear the pump running, it may have a broken or disconnected wire. Accessing the wires is a pain, and I do not recommend you try, since your unit is still under warranty. If you take the unit apart enough to access the fuel pump, you will void your warranty.
Also, if this is an EVAP unit, make you you install the charcoal canister in accordance with the instructions.
If this is a non-EVAP unit, the charcoal canister is not needed.
