I'll Start by saying it is getting spark AND fuel to the motor... ANY SUGGESTION WOULD BE AWESOME!!! Thanks,

Heres the Whole story, I have an S13 with sr20 swap, I melted a piston almost a year ago. It has been sitting outside the whole time. Got another engine thursday, put it in myself over the weekend. got it all in and wired back up. Turned the ignition and it immediately fired up, Ran smooth all was well. Turned it off after about 45 seconds because i had no coolant in the motor. Added coolant started it again. Turned it off, Started it a third time and moved it in the driveway. Now Its in the driveway, About 1/8th of a tank of fuel. I try to start it. It tries to fire once and then nothing. pull the plugs, change them. try again, same thing. Yes i know you arent supposed to, BUT, I try a little starting fluid, still nothing. CRANK CRANK CRANK !!! It finally starts spitting and sputtering then WAH-LAH. It starts! drove it to the gas station, put (20 dollars) about 5 gallons of premium in it (left it running just in case) drive home and it dies pulling in the driveway and wont start, Wash rinse repeat. New plugs AGAIN -> sputters -> crank crank crank -> fires -> runs -> turn it off -> wont start back.Bad Gas???

Is the cylinders getting flooded with fuel?
