for shits and giggles I swapped to the old pump to see how it would run. I noticed when I removed the fuel line from the pump there wasn't much pressure. Tried starting it and did nothing. So I swapped back to the new pump and still didn't have any pressure when removing the fuel line from pump. Read about the fuel pressure regulator and to remove the vac line from the top. did that and it started right but running rough. Did live data on scanner and showed cylinder 2, 3 with misfires. so I thought removing the fuel pressure reg and a coil pack should fix it
