I have a 94 Bonneville, that will not turn the starter. All dummy lights and gauges are working, battery is charged and starter has been tested and working. But when you turn the switch to start, nothing happens. Any ideas what this could be?

One guess, Pull the cover to your shifter and see if the safety ignition interlock cable is broken.

Before pulling things off, check both ends of your battery cables. If they corrode they will still let enough threw to turn on lights, but not enough amps to turn over the starter. So check both ends of both cables. Clean them good and put them back on.

That didn't change anything, but thanks for the idea. I did notice the security light is continuously flashing, could that have anything to do with it?

Is it flashing fast or every few seconds? I believe it should flash every few seconds saying it'* on.

It'* possible the key switch has gone bad. Do you have a chipped key? And are you using that one?

Did you clean both ends of the cables? At the block and at the starter.

Yes cleaned all contacts, it has a chip key. Light flashes steady, but never stops. I am considering replacing key first, it is only $25. The car ran good, then shut it off one day, and never has started again. Everything seems to be working good, dash lights, alarms, headlights, dome lights, windows and power locks. Just seems that power shut of between ignition switch and starter.

Hmm, isn't there a fuse? It should be under the hood on the fire wall.

Checked all fuses and relays on firewall, they are all working. Can hear one relay click when turning switch.

Possible that relay is shot. Did you pull it and test it? It would make sense that the relay is the problem because there seems to be a interuption between the key and the starter.

Yea put a new on in to replace, still no luck...losing hair trying to figure this out.
