Fuel injection problem? Turns over but won't start
 

Replaced plugs and replaced fuel pump. Can hear fuel pump turn on so I think the relays/ fuses are good. I poured a small amount of gas into the front for cylinders (the 4 in the back are a pain to get to), put the plugs back in and I can get it to sputter and almost catch while turning key, but won't fully start. Any ideas what to try next?
