Where are the spark plugs on a 93 Buick Century V6 3300?
There's a different question here with a good answer. (Search for spark plugs on a 93 Buick Century.) Briefly, there are three on the front of the engine (near the cylinders themselves), and three more in back.
How can be removed the spark plugs' plastic protection attached to the engine of a 1989 V6 3300 Buick Century in order to change the front spark plugs' wires?
Typically, spark wires are encased in a flexible plastic tube which is secured in usually 2 places with special clips. The tubing material gets brittle over time and cracks /breaks easily so patience and being careful are the key.

The 3100 SFI engines were rated to 160HP, like the 3300 engines were. The 3.1 MultiPort FI were rated at 140HP.

If a 3.1 MPFI can work in a Chevrolet Cavalier, why wouldn't it work in a Century?

I'm in the same position with a '93 century, had the same problem with my old '89 olds cutlass with the 3.3 or 3300 motor. the best I can tell so far is that one of the parts previously replaced is bad (you can get the ignition modular checked at O'Reillys or simillar) or there is a short somewhere in the wiring - posibly the fuel pump or ignition systems.
