Fuel Injectors not pulsing Sign In

I have a 1993 Chevy pickup with a 5.0 L engine. It is TBI. It quit cranking/running. I can spray starter fluid in it and it fires and runs until the fluid is gone. The fuel pump is pumping fuel to the TB and it has the correct fuel pressure. It has good spark at the plugs.

But I have no injector pulse.

I have tried unplugging the connector at the Throttle Position Sensor and cranking the engine to see if it was stuck in the wide-open position. This did not work. I’m out of ideas or things to check.

Thanks and regards,

James
