Right here we go!!! After 6 hours of bleeding ,cutting out .We had to revert to the dreaded easy start to get her to fire up We believe the New Injection Pump is faulty!!! I say new it was brand new [not a recon ] 8 months ago and it has done less than 20 hrs .Well I say we it should be Martin he got it running for 15 mins .Then it started hunting rvs up/down exactly what it did 4 weeks ago 7 miles out at Sea and I limped it back into the bay ,where I fished all day and it started stopped all good but I never to it over 5 Knots..I did this as I have a outboard for such cases.
I believed the fuel was compromised with diesel bug .{Bit I always use diesel bug inhibitor] I remembered on my last engine it had a bad case of bug and the engine note sounded exactly the same. When I changed the filters they where clean the separator bowl had less than .5''of water in it.
We checked and checked again the for air one the connections,Bleeding the bleed screws and injectors as we went.Martin Heated the heater plugs direct from a 115 amp starting battery,You name it he did it.
Once started it will run ok then hunt it may pick the revs /then decrease up 2/3 times then cut out completely .It may run hunt then cut out, it is Very Random.
I will put on a video [it may take a minute as it is on my phone not on the lap top yet] where you can hear the different engine notes but I couldn't catch the actual stalling of the engine on video.
