Electrical issue?

[Schoeny23]

‘96 gtx started and ran when I bought it. I did the carbs and fuel lines, tightened motor mounts and exhaust. When I put it back together went to start and got the two beeps then 4 beeps and then nothing when trying to start. Now I get no beeps and no start. Checked battery and all connections all good. Is there anything simple I could have bumped to cause this problem. Any insight would be greatly appreciated.

Check all your fuses, 3 in the front electrical Box and 2 in the rear electrical Box.
