Ok rocket scientist.
On the back of ignition switch you have:
C POST - Pink . This wire goes to a big block on the firewall under under the dash on the left side where the pink color stops as it splays off into two different colored wires . It comes out of the block inside the engine compartment as a brown wire which goes to the small post on the solenoid that points slightly rearward.
The other wire joined to it at the block is Red with Green . This comes out of the firewall around 12" where it ends up at a 3 prong plug where it comes out the other side the same color then goes to the positive side of the coil.
S POST - Red Blue . This wire will fk you whenever it can . It comes out of the firewall by maybe 12" right behind the engine and goes to a 4 prong plug where it then goes to the neutral safety switch then comes back out to the other prong on the plug as Red Green which continues to the small post on the solenoid that points slightly forward.
You probably don't have the switch, but if you do, put the car in neutral and see if it turns over.
You can bypass this switch if you want by either unplugging it then simply connecting the two wires on the end that come out of the firewall together somehow, OR you may have to do something else . Can't remember right now.
Tell me the colors of all the wires on this plug and what side of the plug they are on.
B POST Yellow . This is full time power . It ties into a big black with Yellow wire which goes to the big front post on the starter solenoid . You should have 12 volts at this wire at the switch irregardless of what position the key is in.
A POST - We hope not to go there.
