Timing/CPS = ?No start?

The CPS being out of alignment can cause the vehicle to not spark in time. If the spark happens too early or too late, it will cause the vehicle to not fire. If by "turning over" you mean not firing, then yes, the cps can cause that. If by "turning over" you mean not spinning the engine at all, then no, it can't.

I found on my car even with the crank shaft pulley and cam shaft pulleys aligned up my car would not start correctly.
I played around with the CPS and still nothing.

I then discovered by using a strobe light that my timing was out by about 180 degrees....... and by turning the cps the starting and idling became better.

To cut a long story short. The previous owner had removed and dismantled the CPS and put it back together incorrectly. One of the bits inside (cant remember what it was called) was back to front..... ie 180 degrees out.

So, try messing with CPS and make sure it is aligned and set correctly.

Cheers
