Engine bay with distributor, spark plug wires, and labeled wires…

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).
