What could be causing my car to not start sometimes and it's not the battery?

The vehicle I have is a 1999 dodge avenger. When the car wont start, I can keep trying to get it to crank over, while holding the gas pedal down and it will eventually start. It will sputter at first sometimes and then it will start after a couple more cranks. I had the fuel pump changed and it's not the problem and the battery is fine. I've been told it could be the ignition switch that is bad. This could be the problem if my vehicles original key isn't being used and had a computerized chip in it, and instead a copied key is being used, that can mess up the switch.so this could be my problem because I am using a non computerized copy key. Also, my car alarm sometimes goes off when it shouldn't and I've been told that this could be causing the problem. I need to figure out how to disarm the alarm wires that may be the reason it is acting goofy. The wiring is under the steering wheel, I've been told, so maybe that's the reason why, when I do keep the gas pedal down, the vehicle starts. The wiring may be getting held down from the alarm . I don't know? The last thing it could be, is some sort of sensor, like I've had in the past from a previous vehicle I owned. I'm already spending money unnecessarily, trying to figure out the dumb things problem. It's driving me crazy!! Please Help!!!!!What could be causing my car to not start sometimes and it's not the battery?99 avengers don't have a chip in key. If the alarm is the horn honking style, it disarms with a switch connected to the door locks. Sounds more like a electrical or spark issue but more likely a fuel delivery issue since you have to hit the gas and it sputters.What could be causing my car to not start sometimes and it's not the battery?You might find out if this dodge has a neutral safety starter switch which can keep it from starting.This has alot to do with it not starting from time to time which is intermediate no starts.Contact a parts store or a repair shop or dealership they can tell you if it has one in the ignition system.hgm20002000@yahoo.comWhat could be causing my car to not start sometimes and it's not the battery?im a girl yes i know but there are many things that could be wrong with it i might not be right but i only know 3 things it could be the coil pack on the side of your motor, spark plugs, or your fuel line could be cloggedWhat could be causing my car to not start sometimes and it's not the battery?I doubt it would be the key, after all it does start, if it was the key it wouldn't start at all, when did you last service it?What could be causing my car to not start sometimes and it's not the battery?take it to a Mitsubishi mechanic. they made it, despite the dodge name.
