Question about 1992 Buick Century
I do have spark , plugs are dry, have proper fuel pressure on fuel rail,brand new fuel filter,fuel pump runs properly.ect Wondering exactly what controls the injectors or why they may not be opening.
One or more of your fuel injectors are defective. I have a 1991 Olds Ciera 3.3L V-6. It had the exact same problem as your car did.I had checked the pressure,which is 40 psi at the fuel rail. I also replaced the fuel filter,checked the crankshaft sensor,and throttle sensor. Still had the same problem. Cleaned the throtte body intake. What i finally found was a bad #4 fuel injector. Take a multimeter,diconnect the electrical connectors of each injector,check the resistence of each injector over the 2 electrical connectors ,they should be between 12 and 14 omes. The ones that are NOT passing the test(or the ones that don't match up),replace. The computor (EMC) ,will not let the engine start,if one or more injectors are defective.

I have been told on some cars that the cam sensor provides the pulses for the fuel injection. Hope it works for Ya!!
