Could literally be a hundred different things. More info is needed...did the car start prior to the tune up? What was done to it? Any mods? Etc.

More info the better, otherwise we have nothing to go on.

Is the battery good? Are you getting full cranking power? Could be a faulty check valve in your fuel pump combined with a weak battery.............

Check fuel pressure at the schrader valve on the fuel rail to make sure your getting proper fuel pressure. ~42 psi I think is correct, someone will chime in with the exact #.

If that checks out good, make sure your getting spark at both the coil and plugs.

You need air, fuel, and ignition.
If the car cranks fine then you should have air.
Check your fuel pressure. Leaving the car in standby will kill your fuel pump, are you getting any whine?
Is there any spark at all? Does it fire?
