First, I am new to this site, so my apologies if I am not posting in the correct place. I have a 1972 JD 2630. I was bush-hogging field when tractor sputtered. Fuel was low, so I put several gallons in. Engine would fire and idle 30 seconds or so, but would not accelerate. Having looked thru threads, I attempted to prime system with primer pump on fuel transfer pump. Pushing the primer lever didn't seem to be doing anything, so I disconnected outgoing fuel line and pumped, to see if fuel was actually moving. I got an occasional squirt of fuel. I believed the pump was bad, and replaced it and filter. Lines are clear, but still not running. Also, primer lever doesn't feel like it is pumping again. I went to the injector pump and removed input line, and cranked engine to verify fuel....nothing happening. :confused3: Suggestions?
