was wondering if somebody can help me out, i have an rb20 s14 and i was driving down the street and my car turned off than i gave it gas and it came back to life, after that i realized my battery light was on so i pull over and take a look... my alternator belt snapped off. next day put a new belt on now the car wont start. it turns over but doesnt even give a little sputter. fuel pump is turning on. i may mention aswell before this happened the car was having what felt like a boost cut but now that i think about it may have been a fuel cut. surely all injectors didnt go bad on me at once right?

Welcome to NICO Club!

Check the fuses and relays. The starter relay and ECCS relay come to mind. When checking fuses, use a voltmeter set to continuity and touch the two metal contacts instead of a visual inspection.

The battery should have a charge to work. If you didn't replace it or charge it, you probably just need to recharge it to get some juice back.

Please let us know how it goes.
