You may have to go to the dealer to have it reprogrammed.

Did you change over the anti-theft module? The anti-theft module must recognize the transponder key. The anti-theft module then gives the ok to enable the starting, fuel, and ignition systems. On older models it's attached to the ignition switch (the part that the lock cylinder goes into). You may also have to change over the PCM (Powertrain Control Module) as well. HTH. -Jim

Is this vehicle a 2001 or 2007? A 2001 Lumina will have GMs VATS security system. Is there a visible chip on the key? -Jim

Luminas made after 2001 were for export outside of the United States only. Your car may be different from U.S. cars. However the PCM (Powertrain Control Module) and BCM (Body Control Module) are two different units. The anti-theft module is different again and will be buried deep in the dash. It's not easy to find at all. This is done on purpose. Most likely it's in the center of the dash close to the firewall behind other components, wiring, etc. HTH. -Jim

Guys.changed only ecu reprogrammed it now problem is that (1)key remote wont respond.when i open door manually by putting key door opens car alarm start until i put key in ignition alarm switch off and antitheft light get away.(2)car crank but wont start check electric in coils all coils firing tested by putting spark plug in all coils 1 by 1 all wotking fine.checked injectors all injectors spraying petrol while cranking engine.guy please help all things that make car start r working fine then what will b ptoblen that car crank but not start.

Ok, hey, hows it going? Still troubles I see. Question I have is how do you know that the injectors are spraying fuel? And another thing we are having a problem with is like what Js08016 had mentioned is the Chevy Lumina wasn't made for resale here in the U.S.A. after 2001. You have an aftermarket 2007 Chevy Lumina wich is quite a span of years. I ask on how you know the injectors are supplying fuel, because if they were, and you have spark, it would fire up & run.

I removed manifold.there is petrol pipe where all 6 injectors are attached. sorry dont know what we call that pipe.so i removed that pipe in which injectors were plugged,told a guy to try to start the engine while he was starting enigine i was looking injectors saw all injectors spraying. Before this i tested all injectors electric test with tester same way.all injectors getting power supply was sure by seeing blink in tester.then i thoght may b injectors faulty.

Good morning, I think hopefully things are looking up on this problem. You have spark & you have fuel & power to the injectors. All good, eliminates the security system for now. So when you removed the manifold, what does it look like inside? Is it all black, carbon-ed up inside there? Any signs of fuel leakage? Sounds like you need to do a fuel pressure test, and a fuel pressure bleed down test so we can verify if there are any problems there. If you would like, If needed I can send pictures of things we are talking about, mail me back & I will have yours....ruohomaki.ron@hotmail.com
