Cadillac Repair: electrical, fuel pump, fuel filter

Question
my '89 sedan deville turns over but will not start. i changed the inline fuel filter . i have no acessory power no lights don't hear the fuel pump.   where should i start to diagnose the problem?

Answer
Hi Rob, I would check all the fuses by the parking brake pedal and below the glovebox area first and then get a shop manual and start tracing the circuits and see where the power stops for the fuel pump. It could be a bad relay, bad ECM, bad fuel pump or a wire or connection in the circuit somewhere. This isn't a fix that can be described here because it would be too lengthly. Bill
