It sounds like a problem in the BCM. Do you have access to a Tech II scanner? This may be a simple reprogram of the BCM.

allready peplaced the bcm and no tec 2 but we do have a modis and a vantage never seem to get the same codes twice

simply put their is no fuel to the injectors but cannot find any reason at all why

has the security light been coming off/on lately? When the key starts wearing out the ignition starts thinking the car is getting stolen. Usually though you start seeing the security light randomly come on/off for awhile before the car wont start.

I've found www.naioa.com has a decent amount of info on it. It's helped me a couple times with my '00 impala.

installed n ew switch but that had no effect at all

I believe it needs a re-program with a Tech II.

todd · 01-17-2010, 08:39 PM

turns out i was a pinched wire between the ignition and the ecm,when it made connection it was not full value the rest of the time the vehicle thaught it was stolen

Glad to see you found it Todd and the "price" to fix it was right.

todd · 01-17-2010, 08:49 PM

4 days shop time !!!!!!!!!!!!!!! the owner had a new turn signall switch installed about 3 days b/4 we got it but neglected to mention that till we found it pinched in the collum after a new switch was installed a new pcm and countless hrs looking for the problem we really ate it on this one but it was a good education

**btfarm** · 01-17-2010, 08:56 PM

Oh... well then I retract what I said. Thought you found all that and did it yourself.
