1999 Pontiac Grand Prix GTP ProblemsIntake Manifold Gasket May Leak Coolant or Engine Oil
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
The fuel pump may fail causing engine to stall and not restart.

I stopped at store last night, went to leave nothing, it does not crank but all the lights come on. Husband tested the battery and it is fine. He even went and bought a new battery. Still nothing. Anyone know what it could be?
