What is your question?
I have a 1992 Oldsmobile, I bought it and changed the plugs and wires then, it wouldn't start, I then went and got a new coil pack it started right up but now, when I go to put it in drive , it just cutts off, some say it is the fuel pump, some say air sensor, how can I know besides paying some high expensive bill at a local repair shop

It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. The engine needs three things to start, fuel (gasoline), ignition (spark) and mechanical integrity (it must develop compression in each cylinder to start ie mechanical components must be in synchronization with each other. If it had run well previous to this no start condition chances are the engine is well mechanically. You could have a vacuum leak causing a lean mixture, you could have low fuel pressure or fuel delivery volume or problems with anyone of a number of sensors. Randomly replacing parts is never cost effective in the long run. You will need to get the problem properly diagnosed or at least look at a workshop manual to find correct test procedures.
