I have a 2001 Pontiac Sunfire with roughly 220000km's on it. She will turn over just fine but will NOT start. I have just changed the fuel pump in it thinking it's not sending fuel through the lines, also because I could not hear the pump whinning over. She has fire, checked that. She still will not run. Turns over just great though.

Welcome to the forum. You need to check for voltage and ground at the fuel pump relay, try to see what is going on? Engine crankiing, do you have primary voltage at the injector/s? If the computer doesn't see an rpm signal, it won't ground the injectors or fuel pump relay, engine cranking. I believe the crank sensor is ok, because you have spark during cranking.
