started running a little rough so changed plugs and wires. Seemed to help but kept getting worse. Watched other videos on YouTube and changed crank sensor. The coil packs were cracked so changed them. It ran good for about 20 minutes the other day. Changed Control Module. Still won't start.
I'm at a loss.
Thanks for any help

Do what you'd do in any Crank, No Start.
Spray some starting fluid into the intake to determine if this is a fuel delivery issue.
Here's how (on Page 2 of this link):

If it starts for a few seconds test the Fuel Pressure (Page 1 of that link).
If it doesn't start check for Spark.
If there's No Spark test that the Coils are getting the right voltage inputs on their circuits.

If any of those voltages inputs are missing test the voltage inputs on the ICM and Crank Sensor.
