OK, been futzing with this for too long and not getting anywhere. Need advice before I end up hiring someone .
Last year when I was using my tractor I had zero issues with it starting. first or second crank and it fired right up. Then I parked it for a couple of weeks.....and our story begins.
It would fire on the first crank and then no ignition. let it sit, lay on the thermo start for a while, and same thing, single ignition and then nothing. tried a few different times over the winter (as warm as it was) and nothing. plugged in the block heater for half a day and no change in symptoms. last time I cranked it for quite a while and finally gave up figuring I had to have a hard air blockage in one of the lines.
So today, I went through and checked/bled the lines. No air that I could tell, got fuel at the check points all the way to the injectors. Now, one of the injectors appeared to have less flow to it than the other, but there was fuel. Same symptoms, it will crank with no ignition.
(One thing to note is that I was not able to loosen one of the injector lines at the pump. I think the bloody thing was cross threaded by a previous owner and the coupler won't budge. however, there is good flow in that line at the injector, so I stopped worrying about it. )
If this were a gasoline engine I'd be checking for spark at this point.
Short of a complete fuel system tear down and rebuild (which I don't even know if I could get replacement parts for) what's my next step? I'm not a mechanic but this shouldn't be this difficult. Do I need to pull the injectors and look there? Fuel was fresh a couple of months ago with anti-gel/stabilizer added.
Advice is appreciated.
