dont even know where to start....im stuck help

I am fed up with my motor runnin like ****! I jump the A and B obd1 port under the dash to show codes and nothin will blink the check engine light just stays on. Also one of my fans kicks on as soon as i turn the key on and it will never shut off. When i can get the motor to start it only runs on 7 cylinders and it smells very rich.....the intake screams like crazy so i know the IAC must be way off. i have tryed to jump the A and B and pull the IAC and Timming light with the key on to reset the IAC but i dont think it did anythin. I have tunnerpro RT and the Ostrich to tune with but not sure where to even start with this POS haha just upsets me that it wont even idle very well at all! any help would be great at this point thanks guys

Re: dont even know where to start....im stuck help

Turn the key to on position without starting the car and listen for the fuel pump to energize...if there's a delay or you don't hear it there might be a problem in the ignition switch which might fool the ecm into thinking the ignition is not on...no codes will flash. As far as the 7 cylinders...do you know which one is not firing? Is it an electrical, fuel delivery, or mechanical problem? Without specifics it's hard to diagnose, but in a case of multiple failures like yours, I would focus on one problem at a time. Start with the dead cylinder...9 times out of 10 it's a simple fix.
