your ecu is shut.... the programming sends the 2 sec delay for the pump to pressurize... if it still pump before you start, the ecu is shorted !...for sure !!.... get another one from any 87-88 sentra with manual tranny... be sure its a manual tranny!!!...  the wiring itself wont short the ecu... well it as a fuse on it so it should blow out before the ecu.... you probably have some bad condensator on it that went capout !!... does it smell like rotten eggs ????... if yes, those condensator are gone... and the pcb is gone too.... nothing can be done with it... those thing are filled with some kind of acid that just fuckup the PCB... there isnt much to do with it !!... youll have to change it !!  ...
