hows it going everyone, bare with me as i am still pretty new to all of this.

Today my car started up just fine, no issues, drove it to my chiropractor and then back home. pulling into my neighborhood it just shuts off out of nowhere. now i cant get it to start. i check the battery, all electrical still works, lights, radio, windows. when i have the key turned all lights turn on but there is this buzzing/clicking noise coming from behind my engine bay fuse box, ive done research and ive pulled up things on the fuel pump relay, and also my ECU being bad. where should i begin? i dont want to screw anything up and ive never really done anything that has to do with electrical work. i had my buddy put his ear next to the fuel pump to see if it clicks or primes and he doesnt hear anything.

thanks in advance and any advice is really appreciated, i apologize if this is a noob question. dont want to be stuck without a car.

find the relay that is clicking, then use the RELAY IDENTIFICATION KEY on the fuse box to figure out what relay it is. Report back

i checked the fuel pump fuse and it seems fine, i still cant figure it out. i found something that is clicking and vibrating and its the egr valve or whatever its called, but i unplugged it and it stopped but something further down was still clicking. hope this info can help, i know its not the best description
