Series 2 not grounding

2001 s2000. So my fuel pump won’t turn on. Traced it back to the relay and jumped the a15 pin(fuel pump control) to ground and the pump came on. A friend who’s been a Honda master tech for ages said that if I jump that pin to ground and the pump comes on, the EMS is not grounding. I checked all related grounds I could find. Since it grounds through the harness, I checked all the grounds to the motor and chassis. Could the EMS have gotten wet and be acting finicky? Only thing that could be related is I washed the car after I parked it. Since then, the pump won’t prime. It DID try to prime intermittently for a short time but since then, nothing. I’m trying to also upload the schematic for reference.
