I have been having an intermittent issue with my SHO not starting and last week is died on the freeway. I had the car towed to the dealer to find out what this issue was (because I have just replaced the fuel pump and fuel filter and it didn't solve the issue.) And they have informed me that it is the fuel pump relay and have quoted me a cost of 310.00 to replace it. Does anyone know where this relay is located, how much it costs to buy, and if it is worth doing the job my self? Please help I really need to get this car back on the road. Thanks.
