HELP camaro wont start :(

[SSickLS1]

ok so i had my camaro out today before, ran flawlessly.
go home drained the oil, put the new oil+filter in with the right amount and go to start it to get it off the ramps and it just cranks but wont turn over..
pushed it off so its more level and bam it started, then turned it off again and waited about 20 min to try and leave my house for a cruise and it wont start for the life of me..i have no idea wtf is wrong. car is stock besides headers and has 24k miles. no codes on the dash at all

update: replaced the crank sensor last night, still does the same thing.
i get fuel but no spark

I think there's a fuse for the fuel injection, you might check that. How do you know there's fuel but no spark?

You should also check the ignition relay. If it's going south, that will be the symptom, i.e. no spark.
