Ignition by-pass?  Does it remote start with the key in the ignition?  Tach programming?  What happens when you press the R/S button?  Do the ignition lights come on?  Hood switch going to ground?  Ground sense grounded?*   Voltage between input fuses and your grounding point?

All basic trouble shooting tests.

*A.K.A. Neutral safety switch.

Just saw the first post, yellow goes to ignition, pink wire dis-connects factory alarm during remote start, if you have one.  Orange GWA used for window closers etc.  Do you have climate control?  Your heater  AC and rear defogger;  if  youswitch them on while ignition is off, will they come on when you start the car or retain their settings from the previous engine run?  If so  Brown not needed.

Take a DMM set to to 20VDC, set black probe to your grounding point and red probe to each fused input, should measure 12.6volts. Also make sure (by testing as above) that the starter output is working from the R/S. How many leads coming from the ignition switch?  Are they all wired up and accounted for?  Also from your questions about the wires in the first post, one comment, RTFM

Please stop and see local professional help, if there's a second starter you should have tested for it, it can't help you not knowing the vehicle or the R/S and I'm 5000 miles away. Whether or not there's a second starter on the vehicle is something you should have initially determined. If there is, purple to relay 86, ground to 85, 30amp fused 12v constant to 30 and 87 to second starter.

You still have't mentioned whether it's an auto or manual.
