I would start a new thread about this problem. It could be a number of things that will need to be checked BEFORE you start buying parts. First I would check the Fuel Pressure Regulator located in the front top of the engine compartment. Should have a small vacuum hose attached to it. Remove and sniff. If it leaks fuels when removed or the hose smells to much like fuel , you may have a bad regulator.
You will need to test the function of the main fuel pump under the car and the pre-pump in the tank. No need to remove these items to test to see/hear if they are functioning. Note the in tank pump has a small rubber feed hose that sometimes develops a hole causing it to deliver air instead of fuel to the main pump which in turn makes your main pump work harder, drawing more current and heating up your relay. The in tank pump will need to come out for inspection to check this but if the test show it works but very noisy it could be the problem. There may be other issues too. This is why I suggest you start a new thread so others can add to the check list.
