blazer- spark but no fuel?

[psych0matt]

So I did the plugs and wires on the beast, cuz it needed it bad, and when i got done i went to start it and it just turns over. Thinking I knocked the distributor cap loose I took it off and put it back on nice and tight. so now, i have spark, and it turns over, but it doesn't appear that its pushing out any fuel. and ideas/suggestions? (hopefully i can get this figured out cuz Im supposed to go pick up an engine in Wi tomorrow)

Is the fuel pump running when you turn the key to "run"?

did you recheck the spark plug wire positions? Does backfire or try to run?
