Need Help, Wanting to light this car on fire :-(

I have been working on my LT1 swap for over a year (intermittently) and just dug it out of storage recently. I had a little trouble starting it up but finally got it going and brought it over to the garage to clean the dust off it. When I tried to start it about 2hrs later it wouldn't catch and run. I attempted a couple times and nothing. I let the car sit overnight and tried it the next day and it fired up and ran. I shut it off after it was running, and it wouldn't start up again. I tried it the next day and it fired up, but was not runinng on all cylinders at first, but then it came around and started running on all cylinders. I tried starting the car up the other day and now it won't run. Anyone have any ideas on it?

Check the spark plugs, sounds like they may be fouled

I am voting for fuel. How old is the gas? Are all the injectors spraying? What is the fuel pressure?
