Why are my service vehicile soon lite,brake lite, antibrake lite, and change oil lites on after i start car

You drove with a flashing check engine light and then with it on solid. Flashing check engine light means STOP DRIVING and get it fixed. So this sounds like an abused and neglected car to me. Get the trouble codes read that are stored in the computer. Check for good fuel pressure and spark. Fix one or both.

there is a code set in the ABS computer that will have to be checked out and the same with the check engine light but the code will be in the PCM for that. it could be a damaged sensor/wires at the sensors or if you driving in deep snow it could be causing a false code and there is nothing wrong.

service engine lite is a reminder that vehicle is up for service such as oil change--tune up transmission filter etc,2 ways you didnt specify year of grand am --turn key on not start and pump gas pedal 3x should go out ---other turn on not start and push options on display than bring up service than hit reset

After the pads are changed the lite should go out on its own. This lite
warning has replaced the squealer tab that brake systems used in the past as an alert to the operator Hope this helps

does it make any irregular sounds when its running.

firing order is 1-2-3-4-5-6. Thanks for using FixYa.

You need to reset the oil lite with an oil change or add oil. As for the check engine lite being on you need to read the codes and see why it is on then the repair facility will reset the lite. They come on for a reason.

the dealer have tool to shut the light off but if lite is
on when they do the service they will put it out

Change the relay for the brakes

some one has the bulb in backwords or check the wires they might have them crossed
