Grand AM 2.5 Flooding

I have 1988 Grand am 2.5 duke,When I was driving the car at first during wot the car was missing and running rich and would jerk.My mother was driving it one day and hit a speed bump and heard a sounded like it bottomed out and the motor quietend down and she drove it for about a mile and the car just died. I looked at it and it was flooded really bad.Its got a new o2 sensor and it is giving me code for o2 rich. Ive tried starting it with each sensor unpluged and its still flooding. The evap canister lines are cracked but there is no pressure in the tank. I know its ether fuel pressure regulator or injector or fuel pump.I dont have alot of money to dump into it right now and just want to make sure.

kinda sounds like the injector is stuck open/broken. Watch the injector as someone tries to start the engine to see if its a fine mist or if it appears to be just pooring gas into the TB

i agree sounds like injector is open....

Ok,Ill try that,Dose anyone know how much new injector runs
