1999 Oldsmobile Alero GX 6 Cyl 3.40L
What else could be the problem?
Car lost power an wouldn't start. Changed starter,started with a jump an lose power. Made it a 1/4 mile. Starts on a jump,then dies. Got a new battery. Started,ran it for a while. Then death. Changed alternator,fully charged battery. Ran for a while. Guess what happened next.......Now it'll start up fine an die immediately. Different sized and strength batteries produce different results. Any battery that is supposed to "fit" the car, dies the fastest. It'll always start but won't stay running. Fuel System? Bad Ground? Sensor?
