Most cars nowadays have electric fuel pumps which are located inside the gas tank. Most likely you would gain access to it by way of the trunk or behind the rear seat (look for a removable panel under the carpet) or you would have to remove the gas tank to get to it. Before replacing it I would have the fuel pump pressure tested to make sure that it is bad.

I would buy a fuel pump relay for that particular car. If that relay that you switched with the wiper relay isn't the same exact one then the fuel pump will not work properly. Make sure the right relay is in there. Could also be a clogged fuel filter.
The hard part is removing the fuel thank. This is really stupid, but unfortunately this is the reality, there should be an exes door to the fuel pump in the trunk, just like in the old Lada. So when your fuel tank is on the floor, from here is very easy to replace the pump. With the new pump you will have instructions how to do it. Have fun.
First item to check is the fuel pressure. (is it cold where you are?, could have a frozen fuel line?) Open the fuel filler cap and listen while someone turns the key to the on position. There should be a couple seconds of humming noise when the fuel pump runs. If no noise is heard the fuel pump or the wiring to it is bad. Here's a quick hint and it often works if the fuel pump is the issue. While someone is cranking the engine over with the starter, hit the bottom of the fuel tank with a baseball bat or something similar. Not too hard! Just enough to vibrate the fuel pump into making contact on the armature motor brushes. If this gets the car running it's only very temporary, you will need to replace the fuel pump. I guarantee it will happen again, only you may not be so fortunate the next time.
If you do hear the fuel pump run you will need to check that it is developing pressure. On the fuel rail where the fuel injectors are on the intake manifold the is a fitting where a fuel pressure tester is attached to. There should be 50 to 60 PSI when the key is turned on. If low on pressure you will need a new pump. A partially plugged fuel filter is hard on fuel pumps, it does make them work hard. Replace it too. If your fuel pressure is OK then you will need to find out if your fuel injectors are firing. If you need help with those, let me know here, I doubt we will need to get that far, but just in case.
Try replacing the fuel filter also Has it had a tune up? they need to have the plugs replaced at 100,000 if the fuel filter does not work then the most probable cause is the fuel pump is losing pressure when hot. The pump warms up and the check valve fails to close all the way allowing a now fuel or fuel starvation.
HI ' sounds like a liking fuel pump check valve ,to test install a fuel pressure tester follow instruction on tester ,turn key on don't crank engine over turn key off and back on again note your fuel pressure should be 38 psi to 48 it should keep 20 psi in system after 10 minutes of just siting replace fuel pump if you loose the pressure
Need to verify fuel pressure at the injector rail with the engine cranking and with the key on and engine off. Specification is 55 - 61psi. The pressure should build with one cycle of the key. If the pressure is slow to build up there may be a restriction in the system between the pump and fuel rail .
The system should hold pressure without leaking down. If it leaks down there is a problem. If all is good there Checking for a good blue spark at several plugs to verify the ignition system is working ok. A vacuum leak could also cause a hard start issue.
A bad pick up coil or weak crank sensor can cause hard start issues also.
yea most american made cars have the fuel pump in the tank.....just drop the tank and replace....not that hard to do but you will need a helping hand...not something id attempt on my own......did you check the fuel pump relay and fuse.....that could be i too....try that first its cheaper....hope this helps :)
If the hard grinding noise is a metallic sound only when you start it, sounds like your starter bolts are loose or the starter itself needs replacing. fuel pressure doesnt cause any particular noises like that. If your fuel pressure or pump had problems, your vehicle simply wouldnt start
