It sounds like you have a defective solenoid pack or it is not plugged in correctly, also there is a ground wire for the system on the left side of the transmission you need to check (G100). Also, with you foot on the brake, use one hand to have the key in the crank position and then run the gear selector through the gears to see if the starter motor engages. Here is a video to watch

Please upload a short video in your response of the problem, so I can see what's going on :) Check out the images (below).
