2000 Buick Regal car wont start

OK so the car won't start, does it crank? If so check for spark at all plugs, but remove the fuel pump relay or fuse so you dont ruin the engine. After you know there is gas getting to the injectors.3 things needed for an engine to run are gas at all cylinders, spark at all cylinders and compression in all cylinders, check all thre and let us know whats missing, then we can be of more help!

Check the battery cabel connections at both ends negative clean connections at post and block ends and positive clean at starter post and power distribution center, remove the neg first and install last! I am lookind for the location of your starter enable relay, can't seem to find it, look behind your glove compartment on the firewall for a relay center. If there is not even a click it's either the Battery, or relay. You may need to remove your starter and have it tested, Autozone or any big parts outlet will test it free.

Check ignition and crank items...
