car wont crank

I was having trouble with the key on starting, sometimes the car would not start with the key and the SECURITY light stayed on, after a few minutes the security light would go off and the car would crank and run. I looked for a solution here in the forum and saw a write up where a resistor the same as the key chip would be wired in to make the car think that the it was reading the key.The writer of the post suggested that a car remote star installer could do the job so I took it to one. He said that he knew what to do but after he wired the resistor in place the car would not start at all so I told him to put it back as it was and I would live with the problem. He did as I asked and now the car will not start at all. I put the key in the ignition and all the lights come on as they should when I turn the key the lights go off with the exception of the security light which flashes until the key is removed. Can anyone offer good instructionsi for him to be able to fix the problem. Better still a good set of instructions on how to bypass the key reader with a resistor would be good so that we could give it another try. Thanks.

You really should post this in only the Series II tech section, so all responses to your situation are in just one thread.

I think he's (understandably) panicked.

Len you read the whole thread on that resistor thing, right?  there were recommendations *not* to do that.

In the meantime, check and make sure that the installers rewire has no loose connections.

Get your hands on a Tech II and make sure you are getting a signal from the crank sensor. If not may need to replace it. Using a Tech II you can tell what is going on in the startup sequence. Odds are you just need to replace the ignition switch. Replacing the ig switch, instead of installing a bypass resistor, turns out to be a good idea anyway if only because if the ig switch is worn enough for VATS to quit, although it works it would not be that long before the little reed switches in it fail anyway. The contacts arc and get carboned up.
