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

Please let us know what you find.

Best, Ken
