My 99 buick lasa be keeps shorting out the bottom coil pack I replaced all coil
packs,module plugs and wires the car is running on 4 of 6 cylinder any ideas
where the short could be
Your issue may not be the coil pack but what sends power to the packs themselves, The ECM allows full power to the coils to allow the car to start. You may want to look there for your source of the problem...
Also make sure your wires are soild and have no shorts...
