NEED WIRING DIAGRAM! Only 6 volts to fuel pump

[Trudy]

Hello All...

I have looked everywhere for a wiring diagram for my 2006 Mercruiser 5.7 (carbureted). S/N 0W655983. I purchased the service manual (#31) and it only has the wiring diagrams for the Fuel Injected models!!! Please help!!

I am only getting 6-8 volts to the electric fuel pump. I know it the pump is tied into the Oil Pressure switch, and a relay. Engine runs great with pump hot wired. The full diagram would be very helpful!!

Thank you

This would be the carb fuel pump wiring

If you carb`d the main power comes from the ign circuit (purple) to the pressure switch, to the pump, generally its like this click to enlarge click to enlarge

You guys are the best!!!

I unplugged the Oil Pressure switch. Jumped the 2 terminals and that gave me 14 volts at fuel pump. Replaced the switch and we are good
