    There are a number of reasons that can cause this problem to occur. The list that follows are some of the more likely reasons. However, reasons are NOT limited to the following.
    1) Fuel pump could be faulty
    2) Replace fuel filter
    3)There could also be a problem with your fuel pressure regulator.
    -------You should start with replacing your fuel filter. If this doesn't fix the problem then have your fuel management system checked.

    a bad battery can cause this, it did for me. If over 5 years old get a new one.

    I had this problem, very irritating.Engine finally quit and would not restart. The Fuel Pump in gas tank was replaced finally fixed the problem.

    i just fixed my fuel filter and now im thinkin its the fuel pressure regulator .. and if its not that i guess i have to take it to the shop and have them fix the fuel pump... everytime i start my car i have to manually pump gas with the peddle just to get fuel flowing through my fuel lines... i really hope that its just the fuel PRESSURE regulator.. key word PRESSURE

    for starters it could be your alternator but then also it gets deeper than that.. u have a connecting wire the connects your alternator to your starter and its connected to your battery also.. 3 major parts that keep the electricity flowing through your car to keep it running... check that wire make sure its not corroided.. check your battery terminals make sure they arent corroided ... and finally test your alternator
