Are you trying to fix an ongoing problem or something which just cropped up?

Are you aware of whether the car has either the factory alarm or the Clutch Interlock Switch?

If you have an alarm there would be a relay next to the Main Relay called the Starter Cut Relay. This relay has but one plug w/four wires while the other relay (Main Relay) would have two plugs ( 4 wire plug and a 2 wire plug). If you do not have the Starter Cut Relay then you will have a Blue plug with a few wires such as Black/Green, Black/White and a smaller gauge Green wire and this plug would be located close to the trailing coil. Plug would also have a jumper wire in the back of the plug mating the two thicker gauge wires. Once you find either of these plugs you will find the Black/White wire that runs down to the starter solenoid. Jumper this wire w/voltage and see if it turns the starter over.

And w/key to on do your wipers or turn signals work?

We're not interested in the Main Relay. Okay? We are interested on whether or not the wire from the Blue plug which carries the start signal to the starter solenoid is working or not. Okay?

It's as previously described. Should have no more than four wires feeding one side of the plug and a U shaped jumper wire on the back side of the plug.

The thick Black/Green wire should have voltage w/key to start. Jumper wire passes voltage from B/G to Black/White so both should then have voltage w/key to start. Do they? Start with the thick B/G wire.

What do you mean by "jumped." Did you test the voltage of these two wires w/ignition key to start or some other manner?

Yeah I used a multie meter and with the key to start both showed 3 volts and when I jumped the black white wire to the batterie the starter engaged and cranked the motor

There are two switches on your clutch pedal. The one at the very top has two wires colored Black/Red and a Black/Green. B/R comes from the Ignition Switch and B/G takes this voltage to the Blue plug near the trailing coil. You need to measure the B/R wire w/key to start and it should read much higher than 3 volts.

That one is reading 12.30 volts

Then look at the harness that supplies the two wires to this switch and jumper these two wires so it's B/G to B/R.

You jumper the two wires feeding the switch. Once jumpered it should not matter whether the switch was connected or not.

If the two wires are properly jumpered then w/key to start the voltage you found on the R/B wire jumps to the B/G wire which is jumpered at the Blue plug and that voltage finds its way on to the B/W wire that runs to the starter, so just try to start the car.

It means you have a problem w/the switch on the clutch pedal for the voltage on B/R wire must pass on to the B/G wire in this switch when the key is set to start and the pedal is depressed. If it doesn't then the switch is problematic. If this were the case then you obviously can leave the jumper in place or replace/repair the switch.
