Started the car, ran they wouldnt start again, please Help...

Got the Ls1 started today. started and all was well. turned it off, started again and it ran fine. Went to start it later on and it would just crank. I can smell the fuel, i checked all fuses they seem fine. It just cranks. I can assume no spark but i can not be positive. Any input ? Also i am not sure the serial port is working. would that have anything to do with it ?

I would not think that the ECT sensor would cause it not to run.. did you get your MAF fixed? when you say "floor it" do you mean just press on the pedal or do you mean to the floor? how does the motor run? If you are having to press on the pedal that sounds normal for a PCM that has been setting and running in SD mode.. has you modded the motor? Cam and such

motor is stock. got the maf hooked and power to it. Still saw the maf code today though. Pedal had to be touching the floor before for it to start. Now it seems fine. Still have that ect code, and the fans are always on.
