Need some lsj help
I have a 06 cobalt ss with the supercharged lsj I replaced cam and crank sensor and made sure the lines where aligned up with #4 in top dead center I changed spark plugs and I am getting a p0017 code saying crank and cam correlation the car just cranks and cranks before it starts but there are a few times it fires right up I pulled the cover and the chain seems tight and inline. Does anyone have a idea what could be my problem or what I can try next? Thanks, jeff

There is also a bulliten, PI# PIP4548F that talks about cam reluctors moving on the end of the camshaft. They are a press fit and do not have a keyway on them, and they can rotate slightly on the end of the cam, causing the sensor to think the engine is out of time, when it isnt. The reluctor on the end of the camshaft the sensor reads it off. And that is listed with symptoms p0017 and customer complaint of crank and no start.

The sensor hex usually moves when you try to insert it. I generally remove the end cam cap so you can watch it go in the whole way.
A worn chain won't cause the code. You can be a whole link off either direction before the p0017 pops up.

on the chain, you'd be verifying that the timing is correct. look for the timing instructions online. turn the crank so that the marks on the cam sprockets are aligned with respect to crank TDC. I'd first check that the cmps is correct with respect to #4 compression stroke.
