Car won't start, but turns over, changed fuel filter already

A fuel pump would be a semi difficult job for someone who has no expierience with these things but dont be so quick to jump to conclusions simple way to test for fuel pump not working is to get in the car when its really quiet outside and trn the key to the run position you should hear the fuel pump running inside the vehicle it will be a low humming noise if it is heard the fuel pump is ok if you cant tell have a partner trying cranking the engine while you are under the hood spraying carburator cleaner into the tube where the air filter is if the vehicle starts there is a problem with the fuel pump maybe the wiring maybe a fuse maybe a bad pump so you'll need to figure that out but I have seen a large number of these vehicles that have had crankshaft position sensors fail if the vehicle does not start after the test I described earlier you would need to take it to a professional mechanic to have the no start condition diagnosed as testing these systems and sensors requires the use of scanners and special tools like a lab scope I hope this helps
