2000 Monte Carlo SS. Just bought it three days ago. When checking her out her only issues seemed to be with suspension in the front and back. Started right up. No weird sounds from engine and transmission shifted great. Anyways I get her home and put her in reverse to back her into where she was gonna be parked. She stalled out. I tried restarting her multiple times. Nothing. Only thing I hear is the fuel pump priming. Battery is good. The only codes she throwing are a P0507. I'm a bit stumped. Any ideas?

 

Does the starter turn over at all? If so, does it seem like its trying to catch at all or just spinning endlessly?

Since that's an idle air code, what happens if you give it a little throttle as it cranks? (Just tying to make sure its getting air to go with that fuel)

 

Don't hear anything but a click from the dash and the fuel pump.

 

I would pursue resolving your P0507 code. But you get no action from the starter? If so, how are you certain the battery is good? I can tell you from experience, even if the battery has 12v, does not mean it is good (it might lack the ability to output the required amps).
