Hang in there, the culprit will reveal itself in time.
Also i supect you did the door switch wiring fine but those are not the problem, or at least not the only problem. I supect there is some other problem which is making it not start (like mentioned above possibly starter solenoid, etc)
Ps. I often ask the machines what they need, what can i do to help, and maY i know what the problem is. In time they answer. Machines are divine.
