Problems with 2000 Pontiac Sunfire engine. The vehicle would crank sometimes but not start. On one occasion the vehicle attempted to crank and stalled in the process. The problem continued. The consumer was told that the starter had gone out, maybe there was an electrical problem, or the fuel pump. The fuel pump and sender ring was replaced. There was a burnt coolant smell and the valve cover gasket ruptured leaking oil.
