If it ran for 30 to 45 seconds as you mentioned in your first post then forget the gas rag. At any rate there should be an ether injection point on the dash near your right knee.

I would go to the dealer or NAPA and pick up a new set of fuel filters and oring seals. clean the lower bowls and change the filters making sure the orings are in place properly. Using the hand/manual fuel pump pressure up the fuel system and bleed the air out of the filters using the vents on the top of the canisters. Lightly tap the fuel lines and filters to dislodge any air bubbles, wait a few minutes and pressure up the fuel and check for air a second time. Make sure the bleeders are tight and that the orings on them are okay.

With a vom or continuity light 12v, turn the key on and check for 12 volts from ground to the terminal on the injector pump. You should hear the soleniod valve click faintly and have the voltage present too.

If you have the voltage and can hear the click then assuming the tractor and ambient air temperature is warm enough try to start the tractor. Be carefull not to overheat the starter and put a charger on the battery and get it built back up before proceeding. You might try adding some ether while cranking in some very small burst to see if that will help.

It would also help if you could tell us the serial number or close to it to determine what addendums apply in the manuals. There were some changes made at different points in the s/n, with this we can determine what year your tractor is too.

Get back to us when you perform the above.

Okay. Several things. First, there is the primer lever, that has a bowl that can be unscrewed and removed, which I did. This has the fuel line coming from the tank and has a line out to the fuel filters. Found that there is a screen on top and it has a hole in it. Next at the base of this I found a fair amount of sludge.
Then I removed the fuel line coming from the tank to see if any diesel fuel was evident. Didn't have any.
Looking at the glass bowls, which are still there, when rocking the tractor, the left bowl shows fluid in the bowl and I can't tell on the right one.
So my plan at this point is to get some new fuel filters, get some compressed air, remove the fuel line from the bottom of the tank and drain and flush. Take the compressed air and blow to the first bowl, the one with primer lever, with the fuel line removed at both ends to make sure there is no blockage. Replace the screen and hopefully they'll have a screen at the tractor shop, if not will have to order one. Replace the fuel filters, put some more diesel in, prime the system and do my best to make sure there are no air bubbles in the system and pray.... Will get the serial number on next trip.
