We have a 2000 Oldsmobile intrigue that won't start. The security light is on. We have replaced the starter and the ignition switch, even bought a part off eBay that by passes the passlock, then did the reset procedure and the security light never went off and the car still will not start. It will however start and run for a few seconds but only if you squeeze the relay located in the fuse box under the hood. Not sure if we should replace the ignition cylinder next or what we should do.. please someone help!

Which relay is it?

The security is still active.
