if the car will run with fuel added then you could have a bad fuel pump.check further with more fuel as the pedal is pushed open and the car should run faster.be careful with the fuel test..... warning:sparks from plugs, back fires.
also you do not have to have vehicle running to read codes just to get it to store so they can .... spend the money and get a cheapy scan tool and a book particular to your car. All vehicles 1996 and later us the scan tool you can always sell on e-bay if you no longer need or return to store for credit
