Hello and welcome to JustAnswer!

There are many things that can cause a no spark situation. You could have a bad cam or crank sensor, a wiring issue, the problem could be cam timing, the engine controller may not be awake.

Does the fuel pump run?
Have you used a scan tool to check for ECM communication and for fault codes if communication is possible?

Customer: replied 9 months ago.

Where is the cam sensor located on g 20?
Expert:  sprinkles08 replied 9 months ago.

Anything causing a loss of spark should set a fault code, other than incorrect cam timing. How did you check for codes?

Customer: replied 9 months ago.
My scanner no trouble and in history .
Expert:  sprinkles08 replied 9 months ago.

You do have an actual scan tool then? Are cam and crank sensor signals present and in sync when cranking?

Customer: replied 9 months ago.
No did not check for signal .
