1992 Pontiac Grand AM GT, V6 3.3 liter,170 thousandwith motor replaced, running a Grand AM GT 1993 motor. I have replaced the plugs, wires, igntion control modulator, and the coils. The fuel pump is working and I have replaced the fuel filters twice now, and the car will not start. I have made sure there is fuel in the tank. Is there something that I may be overlooking?

Did you double-check all sensors to be sure they are plugged in? Did you use the wiring harness off your old engine? if not you MUST check the main connectors to be sure they are the exact same.Do you have spark? Injector pulse?

motor was changed before we got the car since we have got it we changed the fuel filter, spark plugs, wires, coils, the computer piece the coils are attatched to, The car ran for a week and all of a sudden won't start, the car has a full tank of gas that's why i'm so confused about why it won't start.
