after sitting the night it occationly will not turn over

If it seems to be okay after it starts and drives a while, you may have a parasitic draw on the system. This is something that remains on, even after the key is off. A sticking relay or even a module that is not powering down can discharge a battery and be intermittent. Also check the glove box, under hood and trunk lights as well as those in the vanity mirrors.

Mine does the same thing every morning. I can only get it to start by rocking hard side ways in my seat. The movement seems to help but don't know why. Wish some one had the answer. What a nuisance. Winter is coming and I don't know what the lower temperatures will cause. Wife wants me to get rid of it but I love the car otherwise.
