1G 1G cranks, sparks, but no start!!

[English_Rugby]

I was driving my DSM down my drive and it cut out. The battery was almost flat, I got a jump, it started and I drove it towards my garage, however, it stalled on the way in and lost all of its power. Since that moment it turns over, sparks, but does not fire at all.. I did not hear my fuel pump when I turned the ignition on, I figured it was probably that so I replaced my fuel pump - this didn't solve the problem. When I crank, I smell gas, but the Air/fuel shows progressively leaner until it goes above 18. I checked all the plugs for spark, and all of the plugs sparked. I am wondering what you guys think of this? By the way, the alternator was on its way out and I replaced that also, so the alternator should be good. Hopefully you can help me the answer to this!
Thanks in advance!

Do you have a check engine light? Could be the cas. You might want to test the coil and ptu just to be sure. Also, look at all the connections where your ecu is. Make sure everything is plugged in, inluding the fuel relay. One more thing, pull out your spark plugs and check them out as well. Could have bad plug(s).

Take the cas out spin it over and listen for your injectors to click if they don't then you cas is bad also make sure the plugs are dry and clean

Yeah cheers, I took out my plugs and they were filthy so I got a new set, then it started but it dies out fairly quickly, like within 10-20 seconds or so, so I figure it might be an intermittent problem with my CAS or my fuel filter? At least she is firing now..
Thanks.

ECT sensor?
ECU?
