Will a mass air flow sensor keep my 93 Pontiac 3300 from starting.While driving it just cut off and would not start. And if it does start it cuts off and will not start back .Fuel pump,fuel filter,crank sensor,have been replaced and the computure has been checked and swaped it out two times.Have checked every wire and fuse. I did take the sensor off the manifold and one of the little wires on the sensor was broke. P.S. The plastic cover on the sensor has been broke for sometime.
