Fuel problems

Hey I have a 87 fiero 2m4 sitting in my garage in hopes of fixing it up, but anyway when my car runs the exhaust smells like pure gasoline and the car runs out of gas quick so I am trying to decide if it is a bad injector or what?????? Basically I want to find out what I should tare apart to fix it. Thank you

Running rich could be caused by some faulty sensors (MAT, TPI, O2) or the cold start injector is leaking/ not shutting off. Is your survice engine light on.? (does it work?) any engine code?
