No fuel pump in the tank. Change the filter, it could be waxed up.

well I replaced the furl filter and still nothing the fuel in the old one looked good and no gelling, I filled the new with ne fuel and nothing. I tryed the lift pump to prime it but i ge no pressure on the lever. I turn the motor over to different spots and try the pump and still no pressure on the lever, It is like it does nothing. How do I test a lift pump please help

Before you throw a lift pump at it, use an air hose and a shop rag in the filler neck to (very lightly) pressurize the fuel tank. We are not pressure testing it - we just want a little positive pressure in there. This will show up any leaks between the tank and the lift pump. It could be as simple as a rusty fuel line or a cracked hose.

To test the lift pump independent of the fuel system, put a short piece of hose on the inlet side of the pump and drop the free end in a coffee can of fuel. Open the bleed screw and pump the primer lever. If you get non-foamy fuel after a couple strokes the pump is working.

Fuel shutoff solenoid?

well I checked the fuel shut off wire looked good, so then i took off the line out of the lift pump were the fuel would come out of on top and turned it over and I did not get no fuel out of it. so that would mean that the lift pump it the proublem right. help please

Check the fuel lines for air leaks as I suggested above.

That's free, a lift pump costs money. If the lines are good and the lift pump won't pull fuel from a can of diesel, then the lift pump is bad.

well i tryed the lines and the can of fuel nothng so i took it off. this is what i found the lever that rides on the cam is not connected to the plungger any more some how it can on done and i dont see a way to hook it back up so itlooks like i need a new one, thanks for all the help now i get to have fun and bleed the ar out of the system fun fun

All you have to do is prime it up with the pump-lever, dis-connect the power to the grid-heaters, give it a breath of ether; it will fire and bleed itself, with no chance of cross-threading a line, etc.
