The first cold morning this winter a couple of weeks ago the car wouldn't start - just a click at the solinoid. I tried to jump the starter and no go, so I swapped in another starter and it started fine. Next cold morning, no start again, checked the connections to the starter and cleaned them, and bang it started again. A couple of mornings later same thing except this time I checked the wiring harness and found some degradation in some wires including the blue/green that runs from the harness to the solinoid. Replaced this wire and retaped some of the harness and bang it starts. Car starts on a really cold morning and the next day and all starts during the day OK. Now today the car doesn't start again, just a click at the solinoid. Cleaned the solinoid connection again, no go, jumped the starter, not making a really good connection and got sparks and clicks but the starter doesn't engage, tried it at the key again and the starter catches and the car starts - go figure. It can't be the gear selector switch because I am getting the solinoid to click. I know the blue /green wire from the harness does not go directly to the solinoid but rather travels up to the driver's side fender in a small harness and goes to a relay? and then back to the starter along with a big red power wire and a couple of other wires that go up to the intake manifold. Any ideas? The only reason I mention the cold is that it only refuses to start after sitting at home overnight, once it starts in the morning all successive starts during the day are fine.
