Good shout on the knock sensor. I'll clean those contacts.

What bothers me is that the solenoid works, ('claps'), when I connect it directly to the battery at over 12v. I've not tested the solenoid at anything under that voltage.
I currently get a not too shabby 11.4v at the solenoid positive, (yellow/white wire), and it doesn't click or clap.

Hmm, now that I think about it I believe I read a board on here somewhere that the solenoid doesn't need 12volts to operate, some have reported it'll work at around 10 volts. I have a spare solenoid from another car. I'll swap that in there and see if it works since maybe the internals in the current one need more volts to operate. Worth a shot...

I'll let you know.

Thanks for the input,

-Steve
