I just did an engine replacement o my Stealth, it's all hooked back up but the damn thing won't start. I have power, but when I turn the key over, I get nothing. We jumped the starter to see if it would fire and the car started, turned it off immediately, but the car will not start from the ignition. When I turn the key to on, the Anti Theft light does not go off, it stays on. Could my starting issue be he Anti Theft system? Any assistance would be greatly appreciated.
