Sorry for a long write up, just trying to be thorough.
I have a gehl 3610 with I believe a 3kr1? engine that's been frustrating me in every way since I bought it 2 years ago... It started with not liking to start in the cold sometimes then at the start of winter last year I brought it home from a job, parked it in my driveway for a week and it wouldn't restart (wasn't even that cold maybe -3C), so I plugged it in ran a diesel heater on it for a while and after fighting it started, moved some stuff around the yard parked it and then a few days later once again wouldn't start and everything I tried failed so it sat all winter.
This spring I got fed up with not having it when I need it so I fought to try and get it running to no prevail. Finally had enough and put new glow plugs in, made sure they are working and after some fighting it fired up, used it a bit then it sat for a week, went out it started alright, used it a few more times off and on and it started alright, then it started sometimes having to crank for a while but still started, then it went back to starting decently.
Then it started taking a while to start again eventually getting worse to where I'd have to fight with it again, now it's back to not starting at all, glow plugs are still working, it had an inline fuel filter between the lift pump and tank, bypassed that still nothing, so I thought maybe lift pump so I put an inline 12v pump in still nothing, it's definitely getting fuel to the injection pump, and when I Crack the injector lines at the head they do squirt fuel but I think not enough? Or maybe I expect more. All these times it does puff black smoke out the exhaust, and some out the intake if I take the tube off...
But just won't fire, I have even tried Ether, that just makes the starter slow down or the engine to ping so I stopped that... I took the valve cover off to see if a valve was stuck and from what I can see all the lifters appear to move up and down, and I can spin them slightly, BUT I did notice after a few revolutions of the engine the very back camlobe has a distinct line right around in the oil coating (where it makes constant light contact with the lifter) but the rest don't, they only seem to contact the actual lobe. Also I know some of these models had fuel shut off solenoids, that appears to be taken completely out of this one so thats not a problem.
What else can I try? Can I use a regular fuel pressure tester to check the fuel pressure? If so what should it be getting. Also what can I use to check compression? My compression tester for gas engines is way to big as it fits spark plugs.
