Question

Answer
OK you need to get a timing light to check the timing on the car. If that shows good, then your timing is fine. You coil pack will be fine too. Now if it doesn't light at all when using it, the coil pack is bad.

Now there is also a possibility that the throttle position indicator.

Since I don't know what engine you have you would need to locate this. The simple test is to just disconnect it. It won't let the engine rev properly but it will start.
