Hi,
I have been doing some troubleshooting in the usual starter solenoid clicking nightmare. Been dealing with this for years and now its gotten to the point where there is about a 10% chance it will start turning the key.

Steps taken so far:

1. New battery (no change)
2. New starter (no change)
3. Pulled starter relay from passenger kick panel, disassembled, cleaned/sanded contacts, reassembled (no change)
4. Replaced ignition switch with brand new Airtex 1S6186 Ignition Switch (no change)
5. Created jumper wire to run from ignition switch harness (pin4 aka white wire) through firewall to solenoid contact on starter. This is to completely eliminate the starter relay, and clutch switch from the equation. (see schematic). (lots of sparks, but no change)

6. Removed jumper wire, reattached oem solenoid starter wire
7. Using xacto knife, stripped small portion of wire insulation off of ignition harness before ignition switch harness adapter (pin 4 aka white wire). Ran jumper cable from positive battery terminal to the stripped white wire. (see schematic) (ignition started!!)

So as you can see, I have gone a little overkill but wanted to work from the starter back and to eliminate all possibilities. The problem has been narrowed down the white power wire to the ignition harness. Trying to track the white wire back leads it going up into higher in the dash. I am wondering if anyone has any pics where the white wire goes. Checked google /ebay pics and can not find any good pictures of this wire/harness.

Any help is appreciated.

To the ignition. Switch.

You could eliminate it by putting a relay in. Or replace either the ignition switch or year the dash apart and replace that wire. Those are basically your only 2 options at this point.

The relay is pretty common as it's the easiest and most common thing done to prevent that.
