Having problems with your 1989 Pontiac Bonneville ?
Cylinder 3 and 6 not firing
\015 Removed injector on both while idling no rpm drop. need to know whats the cause. NEw coil, new wires, new plugs???\015
If you had a shorted ignition coil, it may have damaged the ignition module.Take a coil pack from another spot,plug it in just be sure your new one is good.if it still won't spark replace the module.I've seen these that won't spark cold but run ok hot.You can try to heat the module with a hair drier to see if you get it to work,but even if it does you still need a module...good luck
