I have an intermittant no start condition for several months now.

It will only happen if the car has been sitting for 10+ hours.


The engine will turn but it will not start. There is no spark. I have to roll start the car to start it. Once the car fires I can immediatly turn it off and it will fire right back up.

I have tried changing the coil pack with no effect. I have changed the Camshaft position sensor with no effect. The coil pack ground is tight. The battery is good. I recently replaced the coilpack thinking that was the problem.

I am at a loss as to what could be causing this. I really dont want to have to take it to the dealer (they'll likely [censored] to no end about 'aftermarket parts' causing the problem)


What am I missing here?
