Did you do any diagnostics before you replaced anything? If problem with wiring circuit to any component, replacing the component won't fix it.
If it cranks good but won't start, have a helper crank it, while you visually check for spark at the spark plugs. If no spark we'll check that system. If spark everywhere, use a gage and check proper fuel pressure, I don't care what you replaced. If you have the spider fuel system, that system is noted for problems. Make sure battery has a full charge.
