2006 lincoln ls wont start? where is the fuel pump located

I changed the fuel pump on my 2000 LS a few years ago. The system is kinda odd. The actual electric fuel pump is in the tank on the right side. The tank is directly below the rear seat. If you remove the seat bottom you will find a 6 inch or so cover. Under the cover there is a plastic, threaded collar that locks the fuel pump into the tank. The driver's side also has a pump, but it works only my venturi effect from the electric pump on the other side. This pump is used to equalize the fuel level from left to right. The drive shaft tunnel prevents all but the very top of the tank from communicating left to right. Also, I would go with a factory pump. It comes with the whole pump, connectors, filter, Pickup, etc. I tried a parts house pump at first. It was only $50 less and only came with the motor.
