I am working on a 3 cylinder 25 hp merc with EFI and the engine will not go past 4000rpm. When I first got this motor, there was air being sucked in at the fuel fitting. This has been corrected. The prop had not been changed and I question the fuel pressure on the fuel rail for the injectors. I have hooked a pressure tester to the Schrader valve on top of the fuel rail but got no pressure reading when ignition turned on or cranking. Any help will be appreciated.
