WHY WON'T THE ENGINE START IF IT FIRES UP N ROLLS OVER

1997 Chevrolet Cavalier

1997 cavalier fires up but won't start, it only starts when fuel is thrown in the throttle body. Car turns over good. Fuel regulator changed and fuel pump and fuel filter, wires checked and good fuel pump got primed up. Still nothing injectors are working.

No haven't checked that, is there a way to check it without the noid light, the people who own auto stores over here are retards they don't know what noid lights are

I would use a computer safe test light if your going to test it with a test light. One side of the connector will have power key on engine off. The other side will be a pulsing ground while cranking. If you get a computer safe test light with two aligator clips one for power and one for ground it will tell you if you have power or ground and wont have to swap the aligator clip from power to ground when checking for power and the ground pulse.
