pulled codes

good to doo

hi all, I,m working on my 91sc auto. I get a code 543 which is a fuel pump secondary circuit fault, so what do I look for now? thanks for any help. good to doo.
 
That code sounds suspicious for a 91, I would have expected a 2 digit code, but I suppose it is possible.

I assume the car is not starting and the fuel pump is not running? Fuel pump harness comes up from the tank under the rear seat on the passenger side, then runs over to the drivers side and into the trunk by the fuel pump interlock switch, and there is a relay back there as well.
