Measure the resistance of the pellet on the key. Go to radio shack and get a resistor that matches the resistance of the pellet and solder it into the wires under the steering column.

On the key there is a diode theat the key connects inside the cylinder lock from the lock cyclinder their is two white wires that thread down the collum to the maim collum they plug into the main harness. If this white set of wires is broken or cut anywhere or connected to ground then the security system won't let the car start. A new tumber comes with the white wires and the contacts that touch the key. I remove the new contact wire assembly from the old tumbler and install the new on that came with the new tumbler. I don't use the new tumber as I don't have a key with the diode in it thats right for the car. with the old key in the old tumbler with the new wire and contaacts all assembled the car should reconize the key and run like it used to,

Securetylightison and wont start have fuel/spark trys to run then stops cycle key then start then shuts off admidiatly

your car was build with an anti-theft devise from GM, inside the ignition key is a micro-chip, when you insert the key in the ignition cylinder, the sensor inside the cylinder will measure the resistance of that micro-chip inside the key, if there is a match the engine will start, if no match the computer will think someone is trying to steal your car & shut it off.
try using another ignition key (spare key) if this doesn't work most likely the tiny wire inside the ignition cylinder is broken therefore the ignition cylinder will need to be replaced.

most likely cause is an "open" in the security circuit. usually a broken wire from the ignition cylinder.
try using your spare key before jumping into the cylinder.
