19th – 27th July 2011
Well after a truly lovely first leg we anchored outside the Marina at Scarborough for a nights rest before heading up to Fraser island. Next morning spent on deck doing little jobs and getting used to everything. Wind picked up perfectly but unfortunately the engine didn’t. Neil went through everything methodically and I helped by scouring the forums and engine manuals looking for extra clues. We narrowed it down to the fuel injector pump – a mysterious beastie that if broken can not be repaired by mere cruising mortals. It was broken. I blogged the checklist of how we found out it was broken if anyone is interested… So we needed a tow in, and lucky we had signed up to Coast Guard Rescue!
Long story short they towed us in the next day when it was blowing an absolute hooley and we spent the next week immobile whilst the Diesel Injection specialists did their stuff refurbing the injector pump. We had the 4 injectors overhauled at the same time for good measure and so now they, along with the almost new pump are all set for the next 20+ years. They better be, the dent in our cruising budget was humongous!
Prop is covered in weed from the Manly stay but we’ve no incentive to swim, sea temperature is 16C. Brrrrrrrrr
When it won’t fire up here’s the drill.
Check the stop valve is in the off position and open the throttle to full.
Check the fuel supply – like have you got any?
Before we go pulling everything apart, check the belt is turning the Fuel Injector Pump (IP).
Use the electric pump to check the input to and output from the primary filter is clean and air-free by disconnecting & reconnecting each point.
Working along the fuel line, switch to manual pump and push through to the secondary filter and again check in and out is clean and air-free.
Now we’re at the IP.
Disconnect supply at entrance and check as above to ensure it is not blocked.
Bleed (loosen them open until they drip) IP at the valves and let them run to ensure clean fuel. This is the Low Pressure section of the IP.
Crack (same as bleeding, different name..) the injector nuts -fuel should run clean and air free. This is from the High Pressure area of the IP.
Check the internal “spline” is turning (ie able to create the pressure) by removing the plate cover and watching as you turn the engine over.
are you still with me? Try turn it over again and if still no good then you will need to return at another time for Part II. Good luck and please keep us posted on the outcome! As for us, we’re stuck at the injector nuts as no fuel is coming through. Good news is the spline does turn.
Coast Guard are towing us into the Marina where we’ll get a professional second opinion and probably end up having the IP bench tested. We suspect the stop valve mechanism inside the IP has failed somehow – Neil’s money is on a spring-like component..
We’ll keep you posted.
