Asked by for the 2000 Pontiac Bonneville
could be the module that it is bolted to. it is a common failure when the module fails. the old coil may still be good. you can verify that by replacing the old coil on one of the other coils. if it works there, then your module is at fault.
if you remove the module, you can take it to a parts store and have it tested for free. at pepboys, they have the testor and we use it all the time.
