Try swapping your relays.
They are for the ignition and the starter. Either swap them with your fan relays or with eachother. If you have no crank... prob the starter one is bad. If you have crank but no start. probably the ignition one is bad. They also need to be facing this direction... so you can read them from standing on the drivers side.
Also, check your fuses. There are several fuses that will keep it from starting. Anything to do with the PCM/ECU or ignition. theres one inside i know for sure, i just did it the other day, i believe its a 25.
