Question about 1987 Buick Century
1987 Buick Century, V6, 2.8L will not start. No spark coming from any Dirct Coil Output. Where is and what is the name of the common component for these individual coils?
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

Testimonial: "Coils and plug wires check good. If the ignition switch is bad would it give a symptom of not controlling spark to the coils"
When you talk about checking resistance from coil to coil. Are you talking about putting an ohm meter to the ends of each post of the coils?
