Have you tried spraying a little carb into the throttle body and see if it will start?

Hi, those engine's had a big problem with the crank angle sensor and the ignition module. If there is no injector pulse or spark this is where I would start. Here are some guide to help you.

and

https://www.2carpros.com/articles/how-to-test-an-ignition-system

just to confirm the module is bad.

here is a wiring diagram to help with the testing.

Please let us know what you find.

Best, Ken
