1992 BUICK CENTURY 3.3 V6 NOT GETTING FIRE TO THE PLUGS

could be that your ignition coils arent getting any power to them or they have all died on you. i had a 89 2door century with the 3.3L and it misfired pretty bad because of bad ignition coils or it could all so be a bad sensor like a camshaft or crankshaft.

Try replacing your crankshaft position sensor. I had to fix mine cuz it would stall out randomly and take 20 mins to start back up

I've replaced crank sensor and module
