Fuel Pump problems of the 2001 Subaru Outback

The contact owns a 2001 Subaru Outback. The contact noticed that the engine warning light would consistently illuminate on the instrument control panel. He took the vehicle to the dealer and a technician erased the fuel temperature code. Two weeks after the diagnostic, the contact noticed that the engine warning light had resurfaced on the instrument control panel. He took the vehicle back to the dealer and a technician replaced the knock sensor at the cost of $317. Several days after the repair, the engine warning light illuminated again. He took the vehicle to the dealer again and the technician stated that the fuel temperature sensor needed to be replaced at the cost of $520. The vehicle is currently being repaired. The manufacturer would not assist. The failure mileage was 53,378 and current mileage was 53,923. Updated 10/16/08. Updated the dealer replaced repaired a loose connection at the fuel pump sensor.

I have gone through one head gasket on Jan 2003. The head gasket went out in Dec of 2003 and the whole engine had to be replaced. In January of 2004 I had the overhead camgaskets go out on the car as well as the the oxygen sensor. I have had more issues but it would be a small book. Subaru has been relativly unresponsive even after many phone calls and letters to my concerns. Every part was replaced however there seems to be a poroblem with my new engine since there is now an investigation within Subaru. They refuse to pay the dealership for the new engine replacement which raises the question of was this a new engine or what is wrong with the new engine.
