Often when you change the fuel pump you have to prime the system to get the fuel flowing through. Turn the car over a few times, wait five minutes and repeat. It should start after 3 or 4 attempts. J.

Try a new relay first. This may not be good news if that does not work. If you can find the EEC (computer) and unplug it, then replace the fuse-if it blows you have another cheaper part on the circuit thats bad.
If the fuse does not blow, then the EEC must be shorted.
If you have to replace the EEC you may find a kindly dealer with a cash-for-clunker sitting there to violate. Salvage yards have them, Ebay sells them. I have seen them at swap meets for $20. They are a high price part even rebuilt at Dealers or autoparts stores.

Hello! Does your vehicle have spark? If not; Pull a plug and test for spark. Is the engine in your vehicle supercharged? If not and it is a either the 3.1L or the 3.8L then the lack of fuel flow is caused by a device known as a; "Vapor canister purge valve". If this component is defective (does not purge) fuel will not flow. It can be purchased at most auto part stores for around $25.

SOURCE: 1998 Neon. Fuel pump problems...
Has the car been running one day and won't start the next and thats why you replaced those parts? This may be the distributor ignition modual later then when it is going out can act like its got demon in it. This modualator will shut power down to your fuel pump.
Now you can try something first though. Run a wire from a hot wire to the fuel pump and see if it will start and run while that wire is hooked up.
If it does then you can find a wire that only becomes hot when the key is turned on so the pump won't run all the time and only when the car is running. This is called gerry riggen in the service and not the proper way to do it. You may get an engine line on because of it too which will put the computer into trouble mode and cut your power down. But maybe not. Try it and see what takes place. If it still won't start then we need to look into testing the ignition modualator. Keep me informed and I will be glad to help you in the matter as well. Raz
