ok motor has all new pistons i have 105 to 110 psi have not broke the motor in yet im back to my original problem of will not idle in water runs perfect on the hose i have replaced
bulb
in boat filter
fuel filter and water sep on the motor
both lp pumps
vst filter
had injectors cleaned
new plugs
new crank battery
im thinking computer but want to see what yall think before i spend 1500 on one

I am really not much help on multiple rigged 300s,
but why is it saying some of the oil level switches show on and some off?
and why is this electric oil pump reading low?

I gather that this read out was while it was running on the hose out of the water.

is there something different when it is fired up while in the water?
in other words when the problem shows up

Why is there nothing showing of rail pressure on the last part?
Just you did not pick that to be captured?

[Skeeter21i300]

It's just one 300 on a skeeter and it won't run if in the water not sure about the yds setup I just got it to see if there was any codes but I talked to a guy with the exact same problem and it was the pump in the vst so I will try that

[99yam40]

you need to figure out the software and set it up properly.
seems to me it thinks you have 3 motors and 2 think they are low on oil
