I think you still have a fuel issue. I would do a fuel bleed down test. Fuel pressure should be 56 to 63 lbs. Connect a fuel pressure gauge to the schrader valve on the intake, cycle the key to build up pressure, with the key off, watch the pressure gauge. It should not drop in pressure more than 5 lbs. in 3 minutes. If it does, then that means there is leaking fuel injectors, spider lines or regulator. It is recommended to replace all as a unit.
