If more than one is faulty it will. Generally the car can still start missing a cylinder. I doubt it would just be one. It's easy to check for spark though. Pull the plug out and set them on top of the valve cover. Have someone else turn it over and look for blue spark, best to do it at night when it's really easy to see. If that checks out I'd check for fuel pressure at the fuel rail. Then if all that checks out perhaps the starter or something else going on. How was the car before this happened?

Well the car started fine as it always had the other morning.... Pulled out the drive way, got to the end of the street and once I pulled up to the stop sign it hesitated a little and when I pushed the pedal to pull off it just CUT OFF. Hasn't crunk back up sense  it tries to start but it's not turning over and firing up.

I'd say your distributor is at fault. Check for fuel and spark as Box mentioned above, then report back to us with your findings and we'll help you go from there.

F.Y.I I think the car started giving me symptoms that something was wrong about a week ago with the hesitation because when ever I came to a red light or a stop sign it would hesitate and get the shakes real bad. If I had the AC on I would cut it off and it would calm down with all the shaking. It started to shake so bad the day before it quit running that if I shift it into neutral it would quit hesitating and shaking all together. Whenever it was in park or neutral it ran GREAT |

So if you've replaced all of those things have you determined if you are getting spark?
I've seen issues like this in the past with bad torque converters. -------------------- |

I'm going to try taking the spark plugs out today and having someone else crank the car so I can check to see |
