I have a 2000 Mercury 200 EFI OT157821 is the serial. Overall the motor runs perfect. Problem is, the motor only starts when I poor gas directly into the cylinders, then it’ll fire up and idle just fine, and take off fine. I can hear the pump running when I turn the key on. When the pump is on (at the schrader valve) I get 37psi, when the pump turns off I get 33psi. From what I read my fuel pressure is too spec. Anyone ever encounter this issue? Or know what to start checking? The low pressure pump to the filter also pushes out good fuel once running. I need ideas!
