I have a 2003 hpdi and it wont automatically send oil to the remote tank(on the motor) when the oil level sensor gets low

i have replaced the oil pump in the boat cleaned the tank and replaced the filter

ohm tested the oil level sensor on the motor (good)
the emergency switch works and will transfer oil. But it wont transfer on its own. Trim sensor has been replaced. I cant figure out what else could be wrong.
it had 995 hours then when this issue started the diagnostic reader now says the motor has 3 hours. Could this be a short in the motors computer or wiring harness? The motor runs great when you fill it with oil but after about 20 minutes it runs back out and i have to fill it using the emergency switch
