As far as vehicle not moving, it sounds like the beginning of a transmission problem. You could start with a flush incase there is a sticking valve inside transmission. The vehicle starting hard after filling usually means the purge solenoid is sticking open. The purge solenoid allows fuel vapor back into engine so if it is sticking open it will allow too much fuel vapor causing a hard start. Let me know if you have more questions, thanks.
