Seems you have an involved problem here, so I will try to help. First, when you turn the key on, does the check engine light come on in the cluster. Also, your theft light should turn on for a few seconds and then go out. If it flashes, then your problem is in the PATS or antitheft system. Next, go back to the coil. You should have power on the RD/Lg wire with the key on. When you spin the engine over, you should get a pulse signal on the other three wires, this is the signal from the crank sensor to the pcm to let it know what engine rpm is. It closes the field on the coil and that is what causes it to fire the spark plugs. Check to see if you have 12 volts on one side of the injectors, they will not fire if you do not get a crank signal.
Check these things and let's see what you find out.
