if you have no check engine light when you turn the key on and the bulb is still good then you have a computer issue.

Sounds like the CPS. make sure its clean and connected. Check with a multimeter if possible . If you have changed all the ignition stuff that's the next thing I would ckeck.
It sends the signal to the controller for spark.
