My lumina has been sitting for awhile in the garage. I left a door open and the battery drained. I tried charging the battery which didn't work, so I put in a new one. The starter cranks now but won't turn over the engine. Anybody have a suggestion of what to try next? Spark plugs? Crankshaft sensor? Shop for testing?

Feul pump? Can you hear it prime the feul system when you turn the key on? If not id try hitting the bottom of the feul tank with a rubber mallot. How long was it sitting? It might just be bad gas. Could try some octane booster and feul system additives.

thanks for the info...i got it started after using some octane boost and rocking the vehicle a little to mix it up. It seemed to work as I was able start it after...now, for the pads and rotors...
