Okay I have already checked the obvious spark plug, ignition wires, fuel but in my 1990 sidekick that has been sitting for probably 2 years and not started in about 6 months I kind of need someones direction am I missing something? I have to admit I am not an auto mech. but not afraid of working on my own stuff but kinda need some guidance.

1) do you have  visible  spark , fuel and such ?

2) check and make sure you Cam is turning  when you crank the engine . .  Just take the  oil cap off and look down inside .
 You may have thrown the timing belt .

3) check and clean your grounds . On  on the firewall . My 89 also had one on each finder and  another back  behind the drivers taillight .
 Make sure they are all clean  and grounding well

Maybe the caps in the computer popped and corroded the traces on the board

Bad Gas?

does it even try to turn over or is the starter not kicking in?

No it turns over just won't start.. I am beginning that it might have something to do with the fuel injectors but have to wait until the weekend to figure out..
