It should start and run if you are using starter fluid, at least until the fluid is used up.
Check some plugs to see if they are wet. If wet, it is an electrical issue, if dry it is fuel issue.
Also, sometimes injectors need a cleaning after a long time of no use, or the impulse wiring could be faulty.
See if you have any codes, active or stored.

How do I check for codes?

good chance the injectors are gummed up and stuck, if it sat for 2 years or so.

Use a spark tester to make sure you're getting a strong spark, and double check that you have the wires on the coil correctly; the pattern is counter intuitive and very easy to get wrong; it has been said that some repair manuals have it wrong.
