Help car troble 1989 camaro iroc

i have a 1989 camaro iroc 5.7l fuel injected car and it ran fine till now its backfireing a lot and dying out when i try to drive it i have it parked now what could be the problem

Is the check engine light on? If not lets go over the basics. How many miles on it? When was the last time you tuned it up? When was the last time you changed the fuel filter?

Trouble spots on this particular car that make your life miserable include the Mass Air Sensor and Coolant Temp Sensor, but before we get into that answer my questions first.
