    Take a jumper wire at the back of the key switch and connect terminals B and A, then take another jumper wire and connect to terminal B and touch terminal S (Start) and see if the engine starts normal. Also right now, when you turn the key to just on (ignition) do the gauges power up? No? Then...

    High Fuel Pressure

    Should you pre-fill with fuel if possible, yes to help avoid pump stress / heat / early wear out… do you have to, no… with many key on key off cycles, it should self prime. http://download.brunswick-marine.com/filereader/file/pdf/5/enen/mercruiser/gasoline/879288300/879288300_5c.pdf

    High Fuel Pressure

I believe you can open the one up on...
