I have the same car. Check your battery state if charge. 2nd Re lock the car with the fob . Let the car sit for 10 minutes and re open with the fob and start the car. Either a battery problem or the anti theft was set. Please let me know what happened.

2005 CTS 3.6 Dead battery, key stuck, service anti theft and nothing happens when you turn key, Ttried everything, ECM reset, key memory reset, charged battery to 12.7 volts, locked door w remote and opened w key, anyway you get the idea. After 3 days of online reading and trying, THIS IS WHAT WORKED, 1. put key into on position 2. removed sarter relay from front fuse panel 3. jumped 1st pin closest to fender and passenger seat with pin that is closest to motor and front fender. I used a paper clip and just made contact long enough for car to start. ran car for five minutes and took key out and everything went back to normal. then I took car to advance auto parts to have engine light reset. if car does not go back to normal you have ECM (car computer) failure. video on YouTube under "no crank, no start"

Connect obd reader and scan codes and clear them. If they go away you did that the first time you wrongly conected wires. If they don’t go away means that problem persists so recheck your job. Maybe they still not connected properly. If they are maybe you actually have problem with oil pressure and ac. Scan and read fault codes. That will help you diagnose it.

Wiring diagrams aren't arranged that way. They're arranged by system, not by location. Read this post. Then rewrite your question and be more specific about which system you're working on.

Had the same problem. 2005 Cadillac CTS with the 3.6L V6 would not start after a oil change. I started looking for wires and stuff that might have been disconnected. That is when I realized that I had also checked the air filter. The hose from the air filter box to the intake had come slightly loose from the intake. The car would not run with an air leak at the air cleaner box box hose. Put the hose on tight and problem fixed.

You're in need of a professional locksmith my friend. e will reset everything with his tools and knowledge so that it works the way it should. When you call said person, tell them the problem so they can bring along what will be needed.

Take it to a qualified repair shop . Would need to hook up a factory scan tool or a professional one , check DTC'S - diagnostic trouble codes instrument cluster , an HVAC - heating & A/C control module . Why did you replace the fuel pump module ? Did you replace the fuel level sending unit ? You should not mess with thing's you have no clue about .

if the knocking is only on the drivers side when you turn to the right then it sounds like you have a drivers side front wheel bearing that needs replacing. also if the bearing is bad enough you won`t have to turn much to get the noise.
