(I realized this is way too long) Short version
1.) Truck stalls after start up, sometimes have to rev up to start.
2.) Fuel pressure gauge bounces from 30-70 psi
3.) Misfire on acceleration from probably 1500-2500 rpm
I'm assuming it has a problem with the IPR or CPS, how can I narrow it down to which one?
Would the IPR somehow cause the pressure to bounce drastically?

------------- Long Version.
Hey, I have a 97 f250 7.3. I had a huge fuel leak in the valley so I made my own fuel bowl delete. Got it all set up and turned out the fuel pump was also leaking out the weep hole. Replaced the pump.
The gauge was bouncing from 50-60 psi after I set the pressure, which is normal.
The next day I started it up first thing in the morning, -20c not plugged in, started great and I shut it off. Couple hours later I went out to start it to warm it up and it just kept stalling and I had to rev it to get it to go. (Block heater was plugged in). It finally started to run and the gauge was bouncing from 30-70.
The truck seemed to run good but after it got warm it was like it was misfiring as I accelerated. And if I shut it off it would stall once I started it back up.
