In a 1991 K2500 pickup, the ignition coil is typically grounded through its mounting bracket to the engine block. The coil's metal casing makes contact with the bracket, which is then connected to the vehicle's ground system. This grounding is essential for the coil to function properly, as it allows for the necessary electrical flow. Additionally, ensuring that the ground connections are clean and secure can help prevent ignition issues.

Try the ignition control module. Had the same problem with mine $36 part fixed it. The ignition control module is in the distributor and so is the pickup coil, but the ignition coil is by the battery. There is a spark test that can be done. If it was already done and couldn't see a spark, then it could be the ignition coil it self , the ignition wire, or any possible electrical connections.
