Stalls and then sometimes runs and stalls again. Extreme missing. Dumping gas.
Checked ignition module, crank module and fuel pressure.

Is the service engine light on? If so, get the codes. Being an OBD1 car, you do not need a scanner to get them, just a paper clip. Here is a guide: https://www.2carpros.com/articles/buick-cadillac-chevy-gmc-oldsmobile-pontiac-gm-1983-1995-obd1-code-definitions-and-retrieval-method
