Need to know if it is standard or automatic.
If you have an automatic transmission, it probably has a forward clutch/band problem.
it will drive but when in reverse it wont move
Is it an automatic or standard? automatic and fluid is not pumping when engine is running
bad transmission
Call a towing company, a mechanic, and a new friend.
It's probably the transmission, either the valve body or the clutch pack. Either way, it means a rebuild of the transmission.
It needs to be in park or neutral to start. All cars have a "safety" switch which prevents starting in gear.
Yes
Stick shift or automatic? any other gears work?
this is a typical problem with berettas, for some reason the bands in the transmission will not hold out after several miles are on the car, have the bands tightened or replaced, and you wont have any more problems
I mean this seriously: Where you can get a good used replacement. There is nothing external that can be the cause, it has had a serious internal failure and either needs overhaul or replacement
does it shift into reverse and wont drive? if so its your tranny it needs to be replaced
