chazglenn3 Posted April 21, 2009 Report Share Posted April 21, 2009 Welcome to the forum! The theft deterrent system has two very fine wires attached to the ignition lock. They are used to read the resistance of the pellet in the key. These are known to break or come loose causing a no start condition. Sounds like your dad's car has a wire coming loose. You can get a factoryshop manual and fix it or have the dealer look at it. I have a 1991 shop manual that I tried to sell on eBay a couple of times. Let me know if you are interested.

You are on the right section. Your ignition key has a resistor with certain resistance which is supposed to complete an electrical security circuit. When it does not happen your car will act up as it does. First, spray some WD-40 on the key and into ignition lock cylinder. See if it helps. In the worst case scenario (that's what I believe is going on) the tiny wires inside the lock cylinder are moving south and will leave your dad stranded some day. You can bypass the security system by integrating a resistor bought at Radio-Shak in the circuit on the car's side. You should measure the resistance of your key and buy something close. Anothrer possibility is replacing the ignition lock cylinder. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

If the wires inside lok cylinder are about to fail, do not repair them. That repair is not going to last, because wires bend when you turn the key. Iwould recommend foling the system with inserted resistor. That's what I and many others have done.

KHE Posted April 22, 2009 Report Share Posted April 22, 2009 There is a fair amount of work in replacing the lock cylinder. You will need to take the new lock cylinder to a locksmith to have him re-key it to your existing keys. That will be cheaper than buying new keys at the stealership. Also, you will need a steering wheel puller and a lock plate compressor in order to take apart the column far enough to access the cylinder.

adallak Posted April 23, 2009 Report Share Posted April 23, 2009 Taking into account you are in Egipt, cheating the system with a resistor would be the best choice. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
