Your problem could be either a clogged fuel filter or a faulty fuel pump. Replacing the fuel filter is relatively simple. The fuel filter is in the fuel line. It is mounted on the frame, under the right rear door. Unlike the mid 80's Caprices, which were attached to the fuel line with flare nuts, the fuel filter on the 90's Caprices attach to the fuel lines with clips and replacement clips are provided with the replacement fuel filter. Before going through the effort of dropping the fuel tank and replacing the fuel pump, check to see if the fuel pump is priming the fuel lines. When the ignition switch is turned to the RUN position, the fuel pump is energized for about 3 seconds. The fuel pump emits a humming sound when first activated. Generally, one can hear this hum from inside the vehicle, but if the fuel pump is exceptionally quite, one may have to position themselves under the fuel tank to hear the noise. I know of one electrical problem that can mask itself as a fuel problem. If the pickup coil is faulty, the engine may quit immediately after ignition.
