have you checked that battery? it seems that it may need replace it might not be keeping a charge, the connectors to the battery could also possibly be corroded as well, which could caue connection problems, i had the sam problem with my old car and it turned out to just be the connection from the cables to the battery due to bolts needing to be tightend or corrosion.

I have a 94 chevy beritta and it keep dieing like it is not getting gas. Not sure if it is fuel filter or fuel pump. Is the fuel pump in the gas tank and if so can you put an external one on?


The fuel pump is in the tank. Generally a fuel pump will not cause a car to intermitently shut off, it will only keep the vehicle from starting in its entirety. To check it, you would want to do a fuel pressure test, as well as a pressure-hold test to make sure the pump is functioning properly. It is not advised to install an external pump.

Check fuel pump pressure and fuel pump regulator. It sounds like you are not getting fuel into the system and if you are you are not getting enough fuel into the system

1991 eldorado wont start


So you put gas down the throttle body and it won't start. Sounds to me like you either have NO SPARK or your plugs are already fuel fouled. Even with you supplying the fuel. it still wont start. FYI, the FUEL FILTER is located by the R/R wheel, and the FUEL PUMP is located IN the fuel tank. Hope this helps
