The contact owns a 2008 Buick Lucerne. The contact started the ignition and a few moments later the engine stalled. The contact was a certified mechanic, who replaced the burned fuel pump relay switch. The failure recurred twice and the vehicle was repaired each time. The manufacturer was not notified of the defect. The approximate failure mileage was 60,000.

Car would not start, and the fuel relay fuse had blown, damaging the fuse box. Fuse was replaced and on Dec 4, 2013 the car would not start again. New fuse block had to be installed. Mechanic's diagnoses said the fuel pump was not receiving good voltage at time, further inspection and testing showed under the rear seal left side fuse block is receiving good voltage but sending a low voltage signal to the fuel pump. Further investigation shows a burnt and melted high resistance connection at the fuel pump relay. Normally, I understand the fuse next to the relay should have blown. Problem seems to stem with the fuse box and there was only one available in the united states on 12/4/2013 which I got. My mechanic was told they are on national backorder and it could take up to 6 months to receive one. So there is an obvious problem with these fuse boxes.
