Cold start issues, which fluid needs a heater?

Injectors are dirt cheap new. Purchase a set , have the pop pressure verified at a local shop then install.

I'm wondering if this would be covered under warranty ... Only issue is getting the tractor to the dealer

Solvent needs to be injected through the injector at very high pressure to clean them on a pop tester machine. This process cleans them out and verifies what pressure they open at, and whether their spray pattern is conical or not; one of the most crucial aspects of injector function. If they fail for pattern or acceptable range of opening pressure, they are most often scrapped.
Do the tests at a diesel repair shop and report back results.
Warranty, possibly, explain to dealer your situation, or take the injector to them for testing.

I know your going in a lot of different directions

If it were mine I would..

#1 Clean out the fuel tank, then refill with good fuel.

#2 Take your filter bowl off, fill it with fuel, and reinstall..on my DK, the petcock on the filter housing has off, on ,and prime..Don't know how your Massey is set up, according to the book on my DK you don't have to fill the bowl, just turn it to prime and crank till it starts, I filled the bowl anyway when I did mine, if I was in your shoes I would fill the bowl... mine fired immediately...if this works, run it on prime till it is running smooth then turn to on.

#3 If no luck with number 2, I would get a helper crack a line loose on a injector while cranking, be careful, put safety glasses on, don't have any open flame nearby, it should spray fuel under pressure out around the fitting...If no fuel, check the plug on the fuel shutoff solenoid, mine is on the front of the IP...You should hear this click on and off with the key...If the solenoid is functioning and you have still don't have fuel under pressure at the injectors, I would suspect IP...or lift pump on your tank if equipped that way, and call the dealer at that point.

If you do have good pressure at the injectors, but no luck or smoke, I would at that point look at the injectors. But I think your going to find your problem is before the injectors.

Good luck:thumbsup:

I would just add that a Mr. Funnel is cheap insurance when adding fuel to your tank. Knock on diesel, I use additive, clean fuel, but just regular heating oil, and no issues. But then again, 8 degrees is as cold as we've gotten. In the barn, I would guess it's never below 15 or so. I liked the block heater I installed on my old Kubota- really seemed to make for easy cold starts, and it was a bear otherwise. Oh, synthetic engine oil is a must, IMHO, if you live in cold place.

Ok ... please view the attached pics. I checked for fuel, and I'm getting fuel to the pump. I don't know the proper nomenclature for these mechanical parts, so please fill me in. I'm guessing these are the injectors ... those 4 nuts/bolts that are right together and would shoot fuel up into the fuel lines. So, I'm calling that the "injector block" ... I'm getting fuel in there, because when I opened them up, there is fuel. I took the "injector bolts" apart and they did not appear to have any foreign material in them. When I turn the key to the "acc" position, I hear the fuel pump clicking like normal, and it is working to fill that "injector block" ... but is there a second pump? Something that moves the fuel at high PSI that maybe isn't working? Is it inside that "injector block" (again, that's what I'm calling it because I have no idea what its called).. ? When I crack those bolts/nuts, fuel "seeps" but never did "shoot" out.

I'm still getting absolutely ZERO fuel up into those lines because there's isn't a puff of smoke coming when I crank her.

Oh, and please, feel free to "Doctor" my photo to properly label the components I need to be involved with.

I'm open to suggestions...

I'm wondering if... if there is an internal high pressure pump, that it could have been damaged by the contaminated fuel, or the moisture... or something like that ...?

Is there any way to warm the whole tractor/engine for 24 hours before trying to start? Could you just tent the engine compartment and run the torpedo heater? If it has been as cold in Michigan as it is in Massachusetts, there really hasn't been a chance for equipment to warm up above freezing in the past three weeks or so. Could there be gelled fuel somewhere in the injectors that just hasn't had a chance to liquify?

Unfortunately, I can't move it to a warmer area... I could try to put a tarp over it and heat it up

I'm no mechanic and I wouldn't ignore the other advice but it does seem less of a hassle to figure out some way to tent the thing and warm it up for 24 hrs before disassembling engine parts.
