1987 Buick Century, V6, 2.8L will not start. No


the 3 coils are mounted to the ignition module and as long as the sensors that signal the module to fire the coils individually are working I would try a module especially if all 3 coils are not firing..also if you have an ohmmeter for checking electrical resistance, the spec for the coils are 5000 to7000 ohms, measured between each coil from tower to tower (ie) #1and#4 2+5 and 3+6 any more than that and the coils are toasted..lol hope this helps also check the spark plug wires at each end maximum resistance is no more than 1000 ohms per inch,,,good luck

1988 buick century dies when put in gear


Sounds like the lock up torque convertor in the transmission is stuck in the engaged position.There is a sensor switch under the hood that can be temporarily unpluged but leaving it unplugged can ruin the transmission. Take it to a tranny shop.
