1990 OMC Cobra 4.3L V6 Mod# 432APRRGD Fuel and electrical problems/questions
I picked up a 1991 Hurricane deck boat. It has the OMC engine listed above. I am not getting fuel to the carb and have some questions.
1) First observation is that the float on the carb is not moving but is not stuck. I know is electronic. Looks like a holly 2 barrel that came with the engine originally. What should the voltage be across the solenoid to actuate it?
2) Would love a wiring diagram that shows how the battery and engine should be wired to all the solenoids for it. Is there a repair manual available I can purchase somewhere that will give me this information? Just want to make sure everything is wired up.
3) I know the fuel pump is mechanical in nature. I think the part number is 982997???? Other than disconnecting the fuel line is there any other way to check it? I did replace the fuel filter to eliminate it from the problem. All the lines and hoses look good. Just no fuel?
4) I tried to start the engine by pouring some fuel down the carb but did not even try to crank up. Everything is turning as it should and plugs getting spark but not even a sputter from the fuel I gave it manually. Would the electronic part is the carb effect this? Can their be a problem with the ignition switch that might cause this? How to check both?
Thanks for taking the time to help.
