The easiest direction would be to ….
Check if you have the basics:
Any present or stored or history codes
Spark present (Using a spark tester or similar method)
Fuel delivery (listen for the fuel pump also check fuel pressure at the rail)
You stated compression test was done so that is checked off.
Crank signal also crank / cam correlation. ( Need a good quality scan tool)
