Maxima Forums - HELP!!!!!! My car won't start, Please Help.

Ok heres the deal, my car has had many problems in the past with starting and Ive had to fix a lot of stuff, such as the starter, battery, alternator. Now heres the problem.... When I try and start the car, I can hear it try to turn over but it wont kick on, even when I try to pump the gas nothing happens at all. I was finally able to almost get it started for a second and the only way for the car to get running was for me to feed the car gas and when I stopped feeding the car gas it would just shut off. What does everyone think it could be? I've had this kind of problems before with luck starting it after letting it sit for a while. Also sometimes in the morning I have to lightly tap the gas to get the car to start easy. Could it be fuel injectors? Sparkplugs? What? Im clueless, please help me guys I had to leave my car in a random neighborhood tonight and have to figure out what I am going to do tomorrow morning. Thanks.
