- - You said that the engine had a decompression lever - that is how the engine is stopped.
- - You said you were getting diesel
spray from the injectors in an earlier post.
- - You said that the new battery
spun the engine with the decompresson lever closed.
- - It sounded that you had sufficient compression
but a compression
tester would be useful to be sure.
- - Basically two things are left - Fuel supply to injector pump
and fuel injection pump "out of timing." For the first one disconnect the fuel supply line line somewhere between the fuel pump
and the injection pump and rotate the engine. You should get a good fuel flow out of the pipe to prove the fuel pump is working.
- - Then the last item is the Fuel Injector Pump
which may be out of timing if somebody fiddled with it. That is a major problem requiring diesel mechanic
and more importantly the engine maintenance
manual. Get the full model number of the engine and its year and you might find the manual either on the internet
or in a dealership.
- - Next best would be to find somebody with the exact same make/model engine and take a photo
of the injection pump and its alignment. Normally the pump has an index mark somewhere along the base where it is bolted to the engine block. Closely examine this area and find the index mark and then do the same with a "sister" engine.
