underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure

If its been a while sense you have chg. fuel filter,DO IT, If still does the same after that, do fuel pressure test, fuel pump might be on its way out. $$$$$. If pump and filter chks. out ok, than maybe its fuel regulator. My best guess its either filter or pump.

Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

I also agree it sounds like a fuel pump issue. Its easiest to remove the box (6 bolts {need impact wrench} disconnect wires at plugs and disconnect gas filler hose) and lift box up. A hoist is easiest but 6 people can lift it easily. The fuel pump can easily then be replaced. Takes about 1 1/2 hrs. to do entire job this way and its so much easier!
Good Luck!

there are two components that you should be looking at one is called a throttle position sensor and the other is a idle air control motor/valve.these two will make the car hard star or not start at all.the are both located in the general area of the intake manifold right where the throttle cable connects.
