Hello. Being a newcomer I hope not to do anything wrong. So hello again.
I am just finishing a 10-year refit of a boat with a BMC 1.5 Engine. 5 years ago, when I had to move the boat the engine started right up and ran well although it had not been running for 5 years.
From then until now:
Broke off a glow plug, which made me take off the head. Had the head plained and valves fitted in. Put in new injectors and new glow plugs, looked at the lift pump. I did not touch the diesel pump. All put together again the engine sat in the basement for 5 years. I turn the crankshaft occasionally
Recently I put it back in the boat and it will not start. It sounds as if it is shortly before starting. (in between running on its own and being helped by the starter).
Blead the system again and again, filter, diesel pump, governor top bleeding valve and pipes. Diesel comes squirting out of pipes. Put in a new main fuel filter and checked all the hoses and diesel pipes. Disattached secondary fuel filter. Engine will not start.
Had a leak in the throttle lever so I put in new seals rings for throttle and stop levers, checked the metering valve. As far as I could see it was not stuck – did not take it out since I was not sure about getting it in again. Engine will not start. If I don’t glow for at least 30 seconds there is no firing at all.
I even put a hot air blower to the air intake. And guess what, engine will not start.
I am a bit frustrated because the damn thing was running fairly good before I started fooling with it, but the glow plugs had to be changed.
Can it be that its not getting enough fuel, can the diesel pump gets clogged up while standing 5 years? Can it be cleaned without taking it apart? I read something about flushing with transmission fluid to unstick a metering valve etc.
Can it be the new injectors? Can I check them myself?
As soon as I get a gage I will check the compression, which should actually be OK.
Does anyone have an idea what might be wrong?
What can I check or do next?
