Check the batter voltage first. If not that check fuse panel under hood for a 100 amp fuse check to see if the fuse is bad or if it has power. Also check fuseable link wire at starter to see if wire is still good. If it is bad, internal short possible on starter, take out and test it. Replace fusible link.

check relay for dash lights. Fuses that blow sometimes destroy relays.

try your fuses etc ect

there is a fuel pump relay under your dash by your left foot behind fuse panel half the size of a pack of smokes that is the problem they cost bout 55 bucks i am 100 percent sure that is the problem i have done like 10 of them myself

Grab a Haynes manual #42014 and on page 4-4 it explains how to test the main relay. The main relay is located up under the instrument panel, attached to a bracket on the left side of the steering column. Also, check the number 1 fuse or the ACG S fuse found in the engine compartment. Both of these fuses are 15 amp.

i have diagram for accord 1993, i cant see the breaker you mentioned, if your relay is ok, its mean that fuse #15 have power 12V and when the ignition is on, the relay have supply 12V to fuse #33, if all this ok, the problm is on your power window main switch, connect a wire supply by 12V to white/yellow wire at power window main switch or test this wire if already have 12V when ignition is on
