Ok here's the deal guys, I have a 94 Z28 Camaro and I was driving down the road one day last week and the car just started running like it was out of gas, you kno like puttin gas in the engine just every once in awhile. Well I have had a bad O2 sensor in the car so it had been ridin a little rough and all but this was completely different. Changed the O2 sensor and put a new fuel filter in it and still doing the same thing. Fuel Pump is coming on so its not that. When you go to start it its turning over but not starting, i guess thats how I would put it. It just cranks and cranks and then when u stop it will somewhat start and have like a popping like trying to get gas in the engine. Anyone can help? I need to have this car running good so I can go to school and see family in other part of state. I was thinking either Bad Fuel Injector or MAP sensor. PLEASE HELP!!!! Dad doesnt think it is the Fuel Injector would welcome any suggestions, I can do some work, but not a whiz like alot of you

 

That's not always true.

I would suggest checking the basics first. Confirm that you are indeed getting fuel and spark. Since you seem to thing it sounds like it's not getting gas, then check the fuel pressure at the rail. With key on and engine off, you should see ~43.5 psi and it should HOLD that pressure. That would be my first check. Get that done and let us know what you find.
