Same, started off cranking slow and not enough to start, checked the starter it's fine, checked the starter relay, it's good, checked ignition, good, battery, good, grounds, good, starter solenoid, good, now it doesn't even turn slow, just clicks. And I don't think it's the solenoid clicking either.
Not for me I have no clue what's going on with mine still. But I have recently noticed that somebody had removed the buttons for the cruise control. Don't know if that could have anything to do with my problem or not, it shouldn't, but maybe.
I dont think mine has cruise control. I bought it a few months ago and it started fine. Then I pulled the engine and transmission to install a new transmission and when i put it back together it just clicks. Usually that points to a starter not getting enough power but if that was the issue then I think it would start if it has jumper cables hooked up to a running car but it still just clicks
