Hi, got a '99 that was working fine last night, went to start this morning and the starter won't crank. Here's what I've done since, battery fine, tried the spare key, jumped power to solenoid, car starts and dies within a few seconds. All lights in dash come on as normal, fuel pump primes with key, and the security light flashes only when the key is turned to the run position, and never goes on solid as other posts have indicated (that's what's throwing me off). I"m assuming it's a security problem, most likely the key tumbler, as the car has over 225,000 on the clock. I'm going to check the resistance through the tumbler at the junction near the base of the column next to make sure it's not open (broken). Any other ideas? Any help is much appreciated. Thanks, Jared
