I have a 2003 Ford Explorer that is hard to start at times. It will start then chug-a-lug and die out. Applying a little pressure to the gas pedal seems to help but it will die out after letting off. It does this in the mornings or after not being started for a few hours. It takes about 5 tries then it runs fine. It doesn't die out (yet) while driving. A fuel injector was replaced about a year ago, but I don't believe that is the problem this time. For that problem, it just lost power but it started fine. Any help would be appreciated.
Check engine soon light is NOT on.
 
three things are needed for combustion. Heat, fuel, air. If one is missing the engine will turn off.

It occurs in the morning it is probably a cold starting problem. Cars are harder to start in the cold because the spark plugs don't always light the fuel fully, the extra throttle increases the current through the spark plugs making them hotter in order to burn more fuel, thus keeping your engine running.

So there is either a problem with your spark plugs, ( they may be old corroded etc) so they won't be hot enough, or your battery or ignition system is not supplying enough current to the spark plugs.

Your best solution is to put in new spark plugs which is quite cheap to do and see if that fixes the problem. If not check the ignition system thoroughly.
 
It sounds like the fuel pump. I'm not positive, but the fuel flow could certainly have an effect.
