I did the key bypass a couple of weeks ago with resisters from Radio Shack.........
everything worked fine for a couple of weeks.....
today I went to start the car and nothing happened and the security light is now on. (its not blinking)

I thought the key bypass was the fix any ideas what happened?

Update.....later in the day.,.....I tried again , nothing,
I let the key on for 10 minutes and tried the car again, it starts now but the security light is still on.

 

recheck the bypass you did to make sure all the wiring connections are still good and making good contact. Did you solder the resistor in or just splice and tape?

 

I soldered them.

 

I'd start by double checking the solder connections and the resistance value. What type of resistor and what wattage did you use? The cheap 1/8 watt carbon resistors at RS are not the highest quality.

If you put in a resistor that was just on the edge of the VATS table value, it could possibly be that the resistance is just off enough to not start.
