Question about Buick Regal
Make sure the grounds are good and clean and tight.You did not specify what engine your vehicle has so if it is a 3.8 then the grounds are just below the module bracket.I am assuming you do not have spark at the coils.If you don`t have spark at the coils then it could be the ignition module that is bad.On the connector on the ignition module the white wire in terminal A is the spark control wire.You should see 5 volts.If not check this wire.It comes from the ECM.Also check the crank sensor and cam sensor.The white and black wire in terminal N you should see 10 volts.
If it is a 3.1 then check the crank sensor.It is in the back of the motor.These will crack and swell up and cause the vehicle to not start.Let me know the problem you are having and I can be of better help.If you do not have spark where are you checking for spark?What motor does your vehicle have?Is the check engine light on?Hope this helps.Let me know.Good luck.

Hello David. There were two engines available in your regal that year. The 3.1 and the 3.8. There were also early and late production differences in the wiring. Looking it up on both engines and early or late production they were all powered by the pink/black wire from a fuse. I suspect there may be more to your question other than "no power" ? These were also prone to losing the ground circuit which is through the base of the module/coil pack. The studs and the nuts that retained them would corrode and break the ground circuit. Leave me a message and I will return to help if you need it. KL
