help D:!! car wont start

I just went outside to leave and when i tried to start my car it wont start. it turns over but doesnt start. if i turn the key i cant hear the fuel pump turn on. it has done this before. i let it sit for a while and it decided to start up. even if i can just wait a while for it to start up i want to get it fixed. any ideas? thank you.

If you hear the fuel pump its not the main relay. check and see if its getting spark.

no no i cant hear the fuel pump
