99 Lincoln continental turn key twice to start

I have a 99 lincoln continental with 200,000miles on it and have replaced the fuel pump 3 times and it seems to fix the problem for about a week before it returns. In order to start the vehicle you have to turn the key to the on position two to three times for it to start. When you turn the vehicle off u can hear a noise from under the hood a whining the gargeing sound. Any help would be greatly appreciated thank you.
