I HAVE A 1992 RODEO THAT IS NOT GETTING ANY FUEL PAST THE THROTTLE BODY INFECTORS. I KNOW THAT FUEL IS GETTING TO THE THROTTLE BODY AND IF STARTING FLUID IS SPRAYED INTO THE THROTTLE BODY IT WILL FIRE. PLUGGED A "NOID LIGHT" INTO THE INJECTORS AND GOT NO SIGNAL AT ALL. I WAS WONDERING IS THERE A HIDDEN RELAY THAT IS PREVENTING THE INJECTORS TO INJECT FUEL?

Hi eagle12364,

Thank you for the donation.

The injectors must have voltage at one of the wires when the ignition switch is turned ON. The pulsing is controlled directly by the PCM and if voltage is available and they do not pulse while cranking, you have a possible fault with the PCM.

Was any repairs done prior to this occurring?
Did you check the PCM harness for loose contacts?
