Check for proper fuel pressure, key on engine off, my info shows 30--50 psi, so if around 40 psi, sounds good. How long since a tune-up? Any applicable trouble codes? Engine cranking do you have spark at the plugs and fuel injector pulse? Engine cranking, check voltage and ground at the fuel pump connector itself. If good voltage and ground with no fuel pump action, have to suspect the fuel pump. Even if you can here the fuel pump run, that doesn't mean it will make correct pressure?
