I need some help with a yanmar
3hm35. I have always found a wealth of information here, so here goes.
The problem: went to restart engines after winter shut down. stbd engine
started fine, however rebuilt 2 years ago.
, however always seemed to run fine for past 3 years. I believe it is in injection pump. started at source and worked my way out, filters clean, replaced feed pump, have great fuel
flow to injection pump. cracked hard lines at fuel pump
, nothing. Removed hard lines and cranked engine, hardly any fuel
appears out of pump. based on manual schematics and that all 3 valves not pumping, could it be fuel cam not turning on shaft (keyway broken) ? or something inside pump??
I did search the threads and the only thing I did and hope hasn't caused a problem is that seacock was open while cranking engine. When engine didn't start right away, I didn't think to close seacock while trouble shooting.
Can anyone help, sure would appreciate any input.
