I had similiar problem with mine one time,come to find out someone tried to get gas out of it with i plastic tube and when they took it out in a hurry they broke the tube off inside and wouldnt let the gas in much when i went to fill it.We took the neck off and found the plastic tube where they tried to sifone gas.

 

so picked the car up today. it turns out above is exactly what happened. some a$$hole tried to syfine ( or how ever you spell it. ) the gas out of the car and tore up all the valves and what not in the tank and filler assembly. i had them drive me down to talk to the mechanic to get the story strait and saw the parts that he replaced. they where trying to get me to pay $300 to split the cost of repair with them. after arguing for and hour and half, i ended up giving the $100 and had them fill the car up and detail it. i feel like i came out ok on the whole thing so im satisfied. i also think it needs new wheel bearings but it came with a 3 month warranty on the drivetrain so im going to work that out on monday.

anyways, thanks a lot for the help everyone a really appreciate it!

ill get some pics up soon.
