Lister Based Generators / Re: Lister LPWS starts once but not again!
« on: April 15, 2024, 07:50:19 PM »
OK at last I have the engine starting reliably from cold. This was with the help of Marine Engine Services/Primrose Engineering (Richard, Sue and Hayden.  In short my governor rail was sticking in the 'fuel off' position. I came to the belief that it was something to do with one of the high pressure fuel pumps but it turned out to be the nylon/plastic "751-10288 GOVERNOR SLEEVE" that was doing the jamming (only when cold).

Bit uncanny! I had become convinced myself that it was the rack and a sticking pump but with little idea of how this creates the problem.

Have you had experience of this yourself?

Lister Based Generators / Lister LPWS starts once but not again!
« on: October 25, 2023, 04:30:03 PM »
A new problem that I can't get my head around.  When cold it starts immediately and then stops in just a second or two.  After that the engine is completely uninterested.

However I have discovered that if I use full throttle for several minutes and very slowly reduce the revs she will happily settle to a tickover. Once hot she will run and restart happily all day.

Any ideas would be appreciated.

I think I need to have the engine in my narrowboat rebuilt or at least have somebody who knows what they are doing have a look at it. 

Is there anybody out there!!  The boat is in a boatyard in Iver, near Heathrow Airport.  The boatyard can crane the engine out if necessary.

Thanks for the reminder about the rack position.  I had removed the spring and had the rack at maximum position, need check that this is at 55.5mm.

All is good, with 6ft scaffolding pole I was able to undo the left-handed retaining bolt on the bottom pulley. Have had the pumps out, freed the two that were jammed and all back with a governor rail that now freely moves back and forth. As I say a good day!

Looking at your video it would appear that one or more of your pumps is seized. That's about the only thing thar will stop the rack moving. (
Thanks, it is good to have that confirmed.

I should add that I did not remove the spigots, I used a regular spanner that cleared the spigot.  I also used the spanner from above (end-on) and turned it with an adjustable spanner. The threads were well formed and lubricated, the injectors were more than happy to come out. I hope yours are the same.

OK the engine turns over clockwise in the pic, so I'm assuming the bolt thread is normal...

I've just taken out the injectors on my LPWS and used a spanner on the flats between the two pipes, they unscrewed without incident.

Thanks. Can i ask another question, my fuel shut-off seems locked in position but the throttle moves freely, are these both linked to the govenor rail? I'm trying to work out why one moves but the other won't.
