Im getting to much fuel my 1992 camaro rs 5.0L 305 v8 TBI. Its running real rich. Ive replaced the cooliant temp sensor, throttle position sensor, fuel pressure regulator, spark plug and wires, distributor cap and rotor, ECC and the ignition coil, idle air control valve and oxygen sensor. How do I fix this problem what else might it be

Check if the injectors are leaking and also test the O2 sensor.

. Ok then the injectors definately arnt leaking. I just replaced the oxygen sensor and its still spraying way too much fuel out of the injectors. It wont even start because its getting so much gas. Can the injectors be bad even tho there spraying exactly the same. Thanks hopefully that helps

It suppose to be spraying in a mist cone shape pattern-not breaking up/puddles

Could also be the fuel pressure regulator leaking too-also test the coolant temperature sensor.

. Hopefully I don't sound stupid but what do I replace if it's over or under 9-13 psi. Is it the injectors or maybe the fuel pump that's bad? Thanks

You need to actually check the fuel pressure to rule out the fuel pump if its within specs-my recommendation is replace the throttle body
