i belive they put it under the seats starting in 90.....if im correct the pump relay should be under the mass airflow sensor near the purge canister..i remember my buddy went through a puddle in his 89 lx and got water in it somehow my dad fixed it and thats where it was..

its weird i went to miss with it again, i put the negative battery, and the fuel pump noise is gone...right when i put the key in ignition switch and put it on start and remove the key the fuel pumpits on again, i'm thinking it doesn't switch off, and the ecu it self reset it when i reput the battery wire in about 30 minutes and up....

the fuel pump relay its under the maf sensor
i bought a new fuel pump relay at the autozone the problem still the same, i'm thinking its the wiring from the ignition key it switch on but won't switch off
