The Passlock security system is the problem. Should be recalled. The resistor workaround at the key isn't always the only problem. I tried it on my 99 Suburban and it didn't do any better with the resister bypass. You need to eliminate the entire security system. Go here http://newrockies.com/?ap_id=craigpeate for a module to bypass the system completely. Buy the pro module for $179 plus shipping and save yourself the hassle of dealing with it ever again. Or you could go to the dealer and have them replace the entire system for over $1000. They will have to replace the key/tumbler/hall effect switch/wiring and EVO-Passlock module to get it right. Check out my profile page for a list of vehicles affected.
Previous answer:
try turn key on for approx 5 min until security light stops flashing then start it, every time you shut the vehicle off you probably have to do it again.
