I was no expert until I had this problem and now I feel as bough I know my tractor's fuel system as well as most mechanics. Not really, but I sure learned a lot and I credit his site.
I would suggest you inspect you primer pump and completely disassemble and clean it. I found this as one of my problems. I had some slime growing in it and prior to. Leaning, it was not effectively pumping fuel. Also, you need to fill up your tank with fuel and don't rely on your gauge. I did and found that it was broken during this process. Without a lot of fuel, you do not get the pressure you need for a good gravity feed. Lastly, you need to bleed at the injector as well as the pump. If you getting a steady and I mean steady stream at his point then you can feel pretty good that fuel is at the injectors.
You definitely need to check your fuses and if the solenoid one is blown, you probably have a bad. Old weather start sensor.
There is a some good posts on this topic, so trying searching around if this does not help.
