Replaced balancer, crank position sensor, cam position sensor, ignition control module, and, coil pack. Engine cranks, has fuel pressure, Weak Spark, no start. Just bought the car had all parts replaced except coil pack which I installed to get spark.
Any suggestions?
 
Upshift light on while cranking? Means no signal from the crank sensor.

Confirmed spark from the coil? Try to use a plug on the end of one of the wires against a ground and see if you get a spark while trying to start - be careful so you don't get bit. If it sparks, take note of the color of the flash.

This no-start walk-thru is for early, but it might help isolate your issue(s): http://mnharms.com/tutorials/disnostart/
 
Some other suggestions since I didn't see these mentioned earlier.

Did you verify proper voltage at the coil pack?

Have you checked your spark plug wires?
