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.

I own a 2006 Buick Lucerne. The vehicle slows as if it is going to stall and cut off, it picks up speed on its own ,and when stopping the vehicle cuts off. It presents a safety hazard in that most of my traveling is done via the expressway. When the car slows down I am at the mercy of the driver behind me. If he is going too fast and tail gates then I am sure to be rear-ended. I have taken this car to the dealership five times,and they could not duplicate the problem. Diagnostics showed nothing. Service department manager drove vehicle while in shop for fifth time and experienced the problem. Because diagnostics still doesn't recognize a problem he says they are having to call in an expert to determine the problem. The car has been in and out of shop since April 3, 2007, and each time the engineers from gm supposedly were in consultation with service department. This problem occurs randomly with no warning. Help!.
