flow and power to the solenoid should retract it and allow fuel to flow. The motor
started and ran fine for a few minutes then stopped dead. I think fuel starvation should have shown as rough running.
I'll dig back into the wiring
and if I can't solve it that way I'll pull the solenoid and remove the needle.
If you pump the manual pump on top of the primary fuel filter
, does it pump? Remember an issue with one where it would suck air.
Crack the injector on the high pressure side and try and start the engine
. Even though the lift
pump will circulate fuel, you will see the difference between the high pressure of the injection pump and the low pressure self priming of the lift
In any case, crack them all like you would prime a non-self priming diesel
, crank and see if you get pressure.
I had Westerbeke
build a new harness for a W46 last year for a couple hundred bucks. The one we replaced had a lot of cracks and corrosion
. Don't count that until you jump the solenoid.
Also, if you find you need an injection pump, I have one on the shelf that is rebuilt for the 2nd gen W46, which you have.
If you are getting fuel squirts while cranking, I would do a compression
test just so you can rule
out head gasket
, etc. and truly concentrate on fuel. Easy to do on that motor. Pull the glow plugs and connect there.
