rough idle and running

Hey guys, I could use some help diagnosing an engine problem with my 2.9 engine. This truck sat for 10+ years, so I've had to replace a lot on it. I've made good progress, but I just can't get the engine running right. It's running really rich and typically stumbles between 3 and 4 thousand...

The fuel pump was going bad so I was expecting this to happen anyways Buy this is when my problems start. I replace the pump and filter and the truck is running...
