Fuel pump location on a '78 cabriolet?

For over 32 years my '78 fuel injected cabriolet has never failed to start until it sat in storage this winter. Normally I start it at least once a month and let it run a bit just to circulate the oil. The spark seems healthy so I suspect the fuel pump. After sitting for week or so all I hear when turn on the ignition without cranking is a single click in the rear of the car, a relay perhaps? Its obvious that the pump is not immersed in the fuel take. Two questions, shouldn't there be at least a few clicks from the pump and where would I find the pump?
