check under the batterie on the right side, there is a relay that tuns on gas pump knock it or heat it. if you turn the key on and you dont here the pump it wont start (relay cost 25$) had the sma thing happen.
Ckeck the relay under the battetie (on the right side) when you turn the key on you should here the gas pump for a few seconds if you dont the relay is not doing the job. try putting some heat or knok it.
I own a MP and its a good buy.
