Case 1835c/ TMD20 engine HELP!!!!!!!!!!!!! NO FUEL

Ok.....I have the TMD20 motor rebuilt and in the skid steer. I have put in ne fuel filter, fresh fuel, new fuel lines. I pulled the drain plug out of the fuel filter that is on the top/side, got fuel there. Tightened it back up. Cracked line loose before the injection pump, got fuel there. Tightened that back up. Now......I cracked the line loose at the injection pump that runs up to the injector, NO fuel.
I did all this just off of the electric fuel pump.
After I realized I didn't have any fuel coming out of the injection pump with just the electric fuel pump, I put in a fresh battery and started cranking on it. Still no fuel.
Now I must tell you that he wiring is a bit sketchy. But the only wire that has anything to do with the fuel system is the 2 wires that run from the fuel pump. On is the ground and the other bolts to the top of the injection pump for the fuel shut-off. Right? Now, for there to be power to the fuel pup I found a wire that is hot while the key on. I hooked this wire to the shut off wire so the fuel pump would could work. Is this correct? I own all the manuals for this Case 1835c Machine and there is only one wire hooked to the injection pump. So how is the electric fuel pump supposed to get power without the positive wire? Any input is greatly appreciated.
 
Sounds like the lift pump has a positive and a ground.

Connect them as you had so the pump will run.

Then run a jumper from the positive on the pump to the run solenoid on the injector pump.

Both need power for the engine to run.
 
There must be 12 volts to the injection pump terminal with the key on, AND while cranking. You will see the other terminal is already grounded on one of the top cover screws. The electric pump should be on at the same time. I got rid of the electric pump on my 1835C as it's not really needed, BUT the tank should be full to make bleeding easier without the pump. Question, when did the engine run last? If it's set any length of time the injection pump MAY have internal parts stuck from the stale fuel inside. My 1835C loader was down two years before I got it going just before Christmas last year. When I repaired and tested the injection pump the metering valve and plungers both were stuck when I tore it down.
 
One more piece of puzzle. If the lines are/were empty, it cah take a long time to purge air out of them. This can overheat the starter. I have used a clean squirt oil can to
fill the lines by loosening them at the pump. and filling from the injector end using contact to "pressurize the fuel into the line till it comes out the loose fitting. Tighten
the fitting at the pump while squirting, then attach it to the injector. (clean clean clean) Jim
 
Well.....
The motor sat disassembled at the machine shop for 7 years before I bought it a month ago.
So maybe I need to take the pump apart?
No biggie, I may go ahead and order a kit foe it to freah'n it up a bit. And good leads on a good kit?
 
Ive got the possitive wire from the pump hooked to the little post the manual says to hook it to. Then the wire that has power when the key is on hooked to it also. So thats right......right?
 
Can someone tell me which Standyne injection pump this is? I am going to go ahead and buy the reseal kit. They are relatively cheap, and Im
sure it could use a freshening up.
