2001 Evinrude FICHT 225 (fhsif)
Engine will crank and idle fine. Once under a load trying to plane out it runs out of power. When it will plane out and I give it some gas it is like it runs out of fuel and will even die on me. I have the software and the only code it will throw is a low voltage but that's only when it finally spits and spudders for a few seconds and quits. Other than that it will not throw any error codes while it's running bad.
All of the injectors click from the lap top. Fuel pump sounds normal. Killed each cylinder out on the muffs and you could audibly tell each time I did that. No holes in my fuel line. Hooked a clear hose to the primer bulb. No air and it will siphon from the tank through this line with no hesitation. I removed the fuel line from the water separator right off the lift pump and if I hold my hand over the line it seems to hold pressure. When I pump the bulb it seems to have a slight bit of air in it. After looking the part up it's a little more expensive to replace to just see.
How could I trouble shoot this moving forward to check if it is the lift pump or I have another major issue. Once again it will idle fine. It's just when I give it some gas at the lake in the water. Runs fine on the trailer with muffs even when I rev the engine. I'm stumped and wondering if this is common or one of the new many issues I have had over the past years.
