That was a video that just may solve my issue. I have the exact same motor. I was not sure whether the injectors were meant to spray whilst starting. Mine are like yours. I know the low- and high-pressure pumps are good and the filter as replaced the lot, low pressure has a Shrader valve and as you mentioned there is none off the high-pressure side as there is no fuel rail. I installed a t-piece Shrader valve in the line from high pressure pump to TBI. Was just about to pull the TBI off but now i thing i need to look at the anti-syphon valve.
Motor used to start for a little bit then idle up and die. Now it barley starts.
Appreciate it!
I’ve had 3 motors not run in the past year or so due to bad anti siphon valves. $10 part. Needed a new one on a 50 Yamaha outboard, my Kohler Generator and a 150hp Yamaha on a hurricane boat.
I'm guessing if the valve line is not blocked then the next thing would be to look at the fuel reg inside the TBI. I believe they are a Rochester?
Sounds like a rough bearing somewhere? Gimble? Belt pulley? Something worse?
I need help with my 2013 5.7 Volvo Penta last year was out in the water running roughly 4000 RPM and came to a complete stop engine turned off tried to turn it on it wouldn’t start again had to get towed I’ve replaced spark plugs, MAP sensor, Knock Sensor, Throttle Control Module, Throttle Body, Ignition Coil, Battery and still can’t get the boat to turn back on! Would you have an idea of what I could be over looking
I have a 2006 Volvo penta 5.7 Gi with a fuel issue. Started by replacing fuel pump due to paint chips in fuel. After that boat ran but dumped fuel in exhaust. Replaced the pressure regulator, set the injectors out to be rebuilt, reinstalled. Now the boat runs good, idles at about 8, accelerated good, ect…but still have raw fuel in exhaust. ?????
Its old fuel in the tank with water our manifold gasket leaks and bad spark plugs and dirty distributor cap and rotor and dirty fuel modjual
parts number for anti siphon?
i broke mine trying to remove it to clean it
What’s that scan tool setup you got going on pal? Any good?
It Is an OBDStar. I sell them. They are pretty good for most engines. Even diesel as well
@4:25 sorry but you lost me at "base it on your best guess" hint; the part number for the tool you need is in the service manual. Fuel pressure isn't something to guess at.
