Does your car have a factory antitheft system like Passlock with an indicator in the instrument panel? Aftermarket security system? Factory security may disable the starting system and/or part of the electronic fuel injection system to prevent theft by turning on a security indicator. Security modes may be; on, off, blinking, flashing. If main power (battery, battery cables and theor connections) have severe corrosion, this may interfere with power getting to the starter.

Out of curiosity, have you tried jumping the starter solenoid directly to the battery to verify the starter actually works?

Lindsey Mahaffey when you say that "all lights come on" do you mean all of them or just the ones that are supposed to come on? All lights is not always a good thing and could be an issue with your PCM. What exact year is it and what engine size?
