I had a question regarding a 2011 Camaro 2SS, im having cranshaft codes coming up, but i've replaced the crankshaft sensor next to the starter and the starter, thinking it could be that but nothing. car turns on fine when cold but when its running and hot, it stuggles to turn on! i've tried everything. from seeing positive and negative cables corroded, or sensors, but not sure where to start!

Sounds like another bad battery/ground cable issue we covered in the "trouble" section of the forum.

Just replaced my battery. Ten years from a battery is pretty good. Loose ground on the side of the block is another place to look. If you can add an extra ground under the car to the trans.

Do a crankshaft position relearn procedure first before going any further with diagnostics, Need a good scan tool to do this, Whenever a CKP sensor is replaced you have to do this procedure.

See my post in another thread (below) from last week. It will guide you on how to perform a crank relearn and not hose your ECM. Another poster to your thread stated "do a crank relearn", it ain't that simple.

I have first-hand experience doing this and it's not complicated but it must be done correctly!

First, you must have HP Tuners software or a similar platform. Not sure if hand-held or pocket tuners can do this, it's a special function in HP Tuners software.

Here's the link to the thread containing my post. Good luck!
