    496mag no start issue.

    Recorded this from one of MUC post Looks like your fuel pressure is good With no 5V the ECM doesn't know much. One thing is if there is a bad sensor the motor would start, but if there is low 5V then all the sensors are feeding bad info and the motor won't start

    496mag no start issue.

    Fuel pressure should be 39 psi but at 35 it should start. Does fuel pressure stay up when the pump stops or does it drop? Use a spark gap tester and check for spark

    The analog gouges are simple enough, need 12 to 14 V, ground and sender providing variable ground. Your reading low so resistance is high or bad connection. Check your connections, voltage and with power OFF measure resistance of sender to helm ground at the gauge

    Electric panel toilet switch

    Well..... normally there is a water pump switch and its just left ON and the pump cycles each time water is needed. Having one mark as toilet maybe done the same way. That said I wouldn't leave either ON when you leave the boat
