I put a noid on several injector connectors, and it doesn’t blink, telling me the driver isn’t grounding.
Since posting the original question, I discovered that the ignition switch had been replaced.
It doesn’t have a resistor key.
It has a VAT module.
My brother-in-law has a 1989 Trans Am GTA.
The fuel injectors won’t fire.
They have power and are constantly grounded.
Put noids on to check and no blinking.
Checked continuity from injector to ECU connector.
The wires are good.
The problem is I have continuity from the injector...
