    2004 BF150 low fuel pressure

    Sorry I either typed in flow or misspelled and it changed to flow. But I did change the fuel sensor/oxygen sensor. The one that screws into the top of the exhaust. I checked the resistance and it was slightly low then I drove it and the code came up after a while of driving. Then I changed it...

    2004 BF150 low fuel pressure

    Yes I did that using my wife’s glass kitchen measuring cup. She wasn’t happy lol. I had to do it twice to get it up to the first measuring mark. I’ll try that again. After 2 key in switches it was with in the parameter. I can’t remember what it was or what it was supposed to be though. It was...

    2004 BF150 low fuel pressure

    I have the Texa marine software. I can kill a cylinder separately. The engine has about 300 hours total on it. Would the 38psi not worry you? I did the regulator test by the book and it seemed fine. It jumped about 5 psi with the small vacuum line off and pinched. I’ll test it later this...

    2004 BF150 low fuel pressure

    Do you think it could be the fuel pressure regulator? I’ve had issues with fuel pumps over the years on different things but not a regulator that I can remember. I changed the plugs before I checked the fuel pressure thinking it may help the rough idle. I can drop a cylinder with my laptop...

    2016 Yamaha F350 water in oil

    What would cause water in the oil other than cracked head/internal engine damage? I checked the compression and 6 cylinders are 170-180 and 1 on one bank is 90 and 1 on the other bank is 120.

    2004 BF150 low fuel pressure

    I have code 48-5 but I have replaced the air flow sensor with a OEM and it didn’t help. I checked the fuel pressure after the fact and I’m getting 38 PSI pretty consistently. When I disconnect the small vacuum line the pressure jumps up to around 43. I replaced the pump with a Quantum...
