slow_305

I have a 1991 camaro with the 305 motor. i don't have any type of security system installed except for the vats. Rarely, when i go to start the car and turn the key nothing will happen and the security light will stay lit if i leave the key in the on position. If i wait like 10 min with out trying to start the car then go to start it, it will start like nothing was wrong. Why is it doing this and how come when i go to start the car all i need is the key to get it past the lock position then if i take the key out and go to start it, it will start sometimes...

Sounds like your ignition cylinder is worn maybe causing the no need for key issue

Inside the cylinder, there is a spring-loaded contact on each side that contacts the sides of the pellet on the key - the springs wear out and thus contacts don't make contact with the pellet - you can bypass vats or replace cylinder. If you replace cylinder, take new dummy key AND old pellet key to ACE Hardware, and get a pellet key cut using the new dummy key for the cut, and using the resistor value from the old pellet key - they are @20 at ACE.

i have searched for hours and i couldn't find anything similar problem that i have and i kinda don't wanna just by pass it.

thanks for the info though i already have gotten 2 different new keys and it still does this problem. your saying i need a new cylinder cause those springs are bad?
