Stuck Injectors can be freed by simply grounding the EEC wire (NOT the red wire) while the key is in RUN. After a few seconds (sometimes up to a couple of minutes), they can be heard to click open, as the heat from being held on warms up & melts the congealed gas inside them. After all of them can be heard to open & close as the ground wire is removed & applied, cycling the fuel pump will push liquid gas through, allowing the engine to be started & run. The longer it runs (especially with injector cleaners added to the gas), the better the injectors will work, and the smoother the engine will run.
Bank-fired injectors (MAP: '85-93 & some '94-95), have either a Tan or Tan/Red (Bank 1) or a White or Tan/Orange (Bank 2) EEC wire; sequential (MAF: some '94-95 & all '96 under 8500GVWR) have a unique wire for each injector that must be grounded (but NEVER the Red wire).
