I do believe there may be 2 separate issues as the non starting was very occasional (every 6mths) or over a year. At one time, when it wouldn't start, the shifter did move. That is why I think it may be two different issues as you suggest. So I guess I need to concentrate on the no start, but they may be intertwined
It will turnover but not start. When I get the click when I step on brake-starts. So, I did replace brake switch. Ive been reading about Main relay. When I turn key I hear a click and fuel pump whir-would that indicate that main relay is working?
