My truck was a hard start because the fuel line was getting air in it. When it did start I would have to peddle down to get it primed and then once I let it idle it would surge up and down just like you describe. Also my truck runs great down the road.
Here are some pics, my primer tube fitting wasn't that loose, just enough to let air in. My plunger would not firm up, but right after tightened the fitting my plunger firmed up in one pull. I started at the pump and checked every fitting for snug working my way back to the tank. If you don't hit it by the tank, others have had pickup tube air leaks inside the tank which would be the next place I checked.
Plunger tube is white in the picture and my plunger is all the way out.
