Hello,
Just to clarify, which year is the Suburban? You selected 1994 but typed in 1984. Which is correct?
The next item you need to check is the ignition control module. It can be tested.
You can take it to your local auto parts store and they have special testers for these modules.
Here is a helpful video of how to replace the module:

The ignition control module located inside the distributor. See attached diagram for your reference.
Please let me know if you have any questions.
Thank you.
