Car not starting with key .

My 88 tc won't start with the key unless I run a a jumper wire from the starter solenoid to the ignition switch, bypassing all the wiring.  I have traced all the wires but the white wire going from the clutch switch. It has the jumper wire to eliminate the clutch start switch for now while I am putting it all back together. I could use the wiring diagram for this if anyone has it. I've gone thru 20 pages in the electrical thread trying to see if anyone else has had this issue.

Did you put the jumper wire in the neutral safety or was this an automatic car that you converted to 5 speed?

It's an 5 speed car . The jumper is under the dash next to gas pedal where it goes to the safety switch is mounted. The red wire with blue stripe goes from the starter solenoid under the dash then to the safety switch into a white wire with a pink stripe. Auto cars had a factory jumper plug in them . The white wire goes to a black 12 pin plug over by the radio on the driver's side floorboard it has 9 pins in it with 3 empty slots. There is also a red /blue stripe wire that come from the ignition key relay on the steering column to the same black 12 pin plug. The 2 wires are right beside each other . I ran a jumper frome the starter solenoid to the red/bs wire in the 12 pin connector and it starts the car but I don't want to run the car this way even though I could.

I'm not quite following you, but if you don't have power on the red/light blue wire out of the ignition switch in the Start position, then I'd suspect the ignition switch itself. Normally you would continue upstream, but if the car can otherwise be hotwired and run with the key in On position, then the ignition switch is likely getting power. So that makes the ignition switch suspect. Ignition switches do fail.

Yeah, I'm not seeing the attachment option any longer besides being able to view my previous attachments.

Unfortunately, the site isn't being very well maintained and has lost a lot of features and participation over the years.

I looked at your pictures you sent. I'm drawing a blank as to what connector you pictured on the floor near the center console that you refer to as having 9 pins and 12 slots. Keep in mind the red/blue wire color is reused for different circuits.

That said, you had a picture of the ignition switch. As a quick test, with the key On and transmission in park or neutral, apply 12+ directly to that wire by backprobing at the ignition switch. I would use a fuse, just in case. If the starter engages, that's pretty good sign the ignition switch is the problem and that everything downstream is fine.

By the way, this car was either converted to a manual or the accelerator pedal swapped. The accelerator pedal for the auto and manual versions are different and yours is from an auto. So there's been more work done to this car.

The car was originally a manual my son's car was an auto he liked the autos gas pedal and swapped them out when he made his a manual . The connector if you look at the picture with the red carpet it's the one that has a blue speaker wire going into it. The red/lb wire in that plug goes straight from the ignition switch, I also put the blue speaker wire in it to show where I'm at. I had a test lead at both points there is 12v when the key is turned to start than 0v when the key is not in start. Everything worked when it was in my son's car and  it should have worked when he swapped it all over so you think.
