Knock sensor problem

I have a strange problem with my 2002 Vette. I replaced the knock sensors due to a fault with the front sensor.
I'm still getting the 327 code on the front sensor but only after I drive it and then restart it.
I suspect a wire issue but everything I could see looked great.
Any other ideas?
Thanks, Roger

Yes I did. I also prepared the moisture barrier that was recommended.

What brand of sensors did you install? Per the thread @Smoken1 shared, myself and another member had zero luck with AC Delco knock sensors.

You might also check the ground wire (pain in the A**) behind the starter on the Eng. block. Had similar headaches and with the help of Mr. Curley
all went fine after that...
