You dig out a test light—barely brighter than a firefly—and probe the injector connector while your buddy cranks the engine. Nothing. No flash. No pulse.
You pull the glovebox. There it is: a silver finned thing, like a mini heatsink. You test for voltage on the brown wire at the resistor pack input. 12V. Good. Output side to injectors: 0V. Toyota Starlet Ep91 Wiring Diagram
The diagram just saved you $500 in guesswork. That resistor pack is dead. Four resistors, one common failure—cracked solder inside from heat cycles. You don’t replace it. You can’t afford one. Instead, you bridge the resistor pack temporarily—the diagram shows you exactly which pins to jumper. It’s not correct, it’ll run rich, but it’ll run . You dig out a test light—barely brighter than
“Ignition or injectors,” you mutter, like you’ve seen your uncle do a hundred times. No pulse
