Oil & Fuel TN75 -- fuel system question

[Partspring]

Just some thoughts...
Start by checking basics. The fuel hand pump has a screen under the cap of hand pump (remove bolt with 10mm wrench) check that screen is clean. It is possible that hand pumping will move enough fuel to bleed but not enough for engine to run. IF screen looks good check that fuel solonoid is getting power. You should hear a click from the solonoid on the back of the injection pump when key is switched on. If not, check that solonoid is plugged in or possible blown fuse. If tractor still will not start you may have to bleed injectors. To do this, loosen injector line AT INJECTOR. (on top of head) Crank engine over like "normal starting" for a few seconds. Stop engine and snug injector line. If engine does not start on first injector, do the same to the next. It may be possible to bleed all injectors though not likely. After bleeding make sure all injector lines are snug and not leaking.
Hope this helps. Dan

In my original post I say that I cracked the injectors meaning I either loosened or completely disconnected the line to the injector. I first started by just cracking the line and then decided it would be best to disconnect. In any event I mistakenly cranked the engine in this state and while there was a bit of fuel at the loose injector line it seemed to me to not be nearly enough...only enough to make a small wet patch. After the initial discharge there was nothing else either when cranking or hand pumping.

I didnt check the screen or electrics...Ill do that when I get back home and see id that makes a diff.

Thanx again for all the ideas/questions...I very much appreciate it.

You do realize that the amount of fuel per injector squirt is -very- little... injector lines won't run a stream and pour out on the ground like a hose... it's very little fuel.. normally under high pop off pressure.. which, with the line cracked.. is reduced to -0-.. thus you have very little fuel under virtually no pressure.. a wet patch sounds about right..

OK, thanx for the heads up. I didnt know that. When I get home Im going to run thru all the steaps again. Im sure it must be something Im doing wrong b/c I dont understand hat to expect.

My old bomb has no bleed screws , it has a plastic clip that holds the fuel pipe into the filter head with an 'O' ring seal . After the filter is primed via removing the pipe . All you can do then is pump the lift pump a couple more times until it builds pressure and goes limp . Not like the good old days with a bleed screw and a prime pump that will keep on pumping .

Got it started but did nothing else exc use the thermostarter several times. Guess all my horsing around put too much fuel into the cylinders...just a guess though. Thanx again for the help...
