Engine Performance problem
1993 Oldsmobile Cutlass 6 cyl Front Wheel Drive Automatic

I just put a new fuel pump on my 93 olds cutless supreme and started the car back up. Smoke started coming out of the tail pipe along with raw gas. I was told that I probably have a fuel injector that was stuck open. The engine is running really choppy. I replaced the plugs and wires, that didn't help though. Can anyone help me out. Any help would be appreciated. If anyone needs more information just let me Know and I will try to provide it. Thanks

Were you having this problem before you replaced the pump? Use a fuel pressure gage, the pressure will come up with the key on, no crank. Watch the pressure, if it drops like a rock, it's draning back through the pump, the return line or the injectors are leaking. The vacuum line to the fuel pressure regulator, any gas in it? Watch out for pressure. Any applicable trouble codes?
