Westerbeke diesel will not start
I cannot get my engine to start. I have a sailboat with a Westerbeke W50. Although the W50 has not been in production for many years, the power plant is a British Leyland 1.8 liter diesel that was used in taxi cabs, narrow boats, and tractors like the case DH4 trencher.
We recently went out for a sail. The engine started and ran flawlessly for about an hour after which time we did a normal engine shut down and sailed without the engine for about four hours. When it was time to restart the engine to power us back to our dock, the engine cranked like normal except it never fired. It acted like it wasnít getting fuel.
In summary, the fuel is good, the vacuum gauge for the fuel filter is reading below 1 psi. and the lift pump checked good at +9 psi. I had the injector pump and injectors checked. The pump and injectors failed to meet spec. (Out of spec, but short of a catastrophic failure; the engine should have run.). I had the injector pump rebuilt and put in a new set of injectors, but this did not get my engine running. I also bench tested the glow plugs and monitored their voltage during the start cycle. The engine cranks like normal, but does not fire off. Iíve bled the system several times and checked that the valves are operating. I checked an injector connected to the fuel line, but not in the cylinder and confirmed it sprayed fuel in bursts like it should. I put a short squirt of brake cleaner in the air intake and got an encouraging short run of a couple of seconds, but the engine would not catch. The engine has 1000 hours since a major rebuild and had ďlike newĒ performance!
Iím humbled and baffled?? Is it possible for the timing chain to have jumped a tooth? Would the engine still crank the same, fire or pop or something? Any suggestions would be greatly appreciated. Also, has anyone found a source or cross reference to British Leyland parts since Westerbeke has limited support?
