HI. Two issues here. The first will be with your fuel pressure regulator. this device can fail, mechanically, thus, causing an inappropriate amount of fuel to be introduced into the system. this will cause flooding, due to a ruptured diaphragm. I recommend to have this device inspected for damage.

The second issue will deal with a failed injector(s). Injectors can fail In this way, as well. This device can become filled will debris, thus, causing the mechanism to not close completely. This will cause flooding, in this case. replace any injector that is damaged in this way(stuck open).
