Hello, I have a 2007 Monte Carlo 3.5 l LT with multiple issues. First the car would not start or crank. I changed all of the passlock devices. Such as the key cylinder, cylinder housing, and the two passlock devices that mount to the cylinder housing. Once that was installed I did the key relearn procedure 10 min with the key in the on position 10 seconds in the off position. I did that 3 times. Still no crank or start. I did that procedure numerous times with no results. Next I reinstalled the passlock key identifier the unit that slides over the key cylinder. Then tried to start and it fired right up. At that point the dash gauges started going wacky. The center of the dash would read theft deterent malfunction, brake system faliure, then the ABS light was on with the security light. The I turned the key to the off position and then tried to restart it and the car would not start. So I waited a while and tried to start it again and it fired up. But it was running like it was starving for fuel. So I read several complaints and they fixed there car with the Newrockies passlock fix module. I bought the module and now it fires up every time and drives nice except it shifts hard in to gear, it still has the theft deter ant message along with the ABS LIGHT and the brake assist message on. Does any one have any ides ?
