Starting problems on BMW 3 after replacing spark plugs and coils

Car won't start

Hi all, I have a 2009 BMW 3 with 100507 km and I am facing a serious problem. The car does not start. Initially, I changed the spark plugs and the car started but misfired. Then, I decided to change the coils, but now the car won't start at all. Has anyone had a similar experience or know what could be causing this problem? I would appreciate any advice or suggestions. thanks!

Check the battery voltage first to ensure it's fully charged, as a weak battery can prevent the car from starting. If the battery is fine, inspect the connections to the coils to ensure they are properly seated and connected. Let me know how it goes or if you have further questions!

I put a new battery but it still does not start, there is no warning light and no code, the only one that appears after scanning is 00A10A.

I put a new battery but it still does not start, there is no warning light and no code, the only one that appears after scanning is 00A10A.

The code 00A10A typically relates to the fuel pump or fuel system. Check if you can hear the fuel pump priming when you turn the ignition on. If not, inspect the fuel pump relay and fuse. If the pump is not working, it might need replacement. Keep me updated on your findings or if you have more questions!
