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

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

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