Hey Guys - been trying to get my Volvo Penta MB7B running but have
not had much luck, so maybe you all can help me with a bit of advice.
Here my story sad but true:
I bought my Vega last November. The diesel ran just fine and I took it
out in December and January. In February I went to the boat and
started it to charge the batteries and run the diesel a little to
keep it limber, well it ran for a short time and then quit. I checked
if I had fuel and there was plenty. I checked the filters and they
were not plugged (even replaced them). There was no contamination in
the fuel so I checked the primary lift pump and it was not pumping. I
replaced the pump and then started bleeding air out of the fuel
lines.
I know I have fuel up to and through the first filter and also fuel
to
the fuel filter located on the motor, no air present in either. I
know I have fuel to the inlet of the injector pump. I bled the
injector pump and then tried to bleed the injectors. No fuel what so
ever was coming out of the injector lines located at the injectors. I
then tried to check and make sure that fuel was coming out of the
injector pump so I removed the line at the discharge of the injector
pump,spun the motor over and no fuel came out of the discharge of the
pump.
I have a sinking feeling my injector pump has gone south. What do you
all think? Is there something I may have missed? Any help would
definately be appreciated. If the injector pump is bad order how much
do these things cost?
