I have a 92 chevy truck with 4.3 v6, automatic trans.
I have no voltage at the throttle body injectors. It has a new computer,electronic module,and pickup coil.
Where do i go from here
Thanks Buster but i also put in a ignition switch after listing here. Anybody got a chevrolet service manual for this vehicle am willing to buy it. Thanks Ricky

have u traced the wires (visually & for continuity) from the computer out to the injectors? i mean physically looking @ the wires each and every inch through-out the harness. i've seen the ground side of the injectors wiring harness corrode @ a splice about 6-10 inches back from the plug.

when u r tracing the wires to the computer, u'll find the same red and blue wires run into the same plug. the wires r 12 gauge (if i remember correctly). while u r checking the voltage for the injector's, remember that the injector's "fire" by switching the ground, so if u haven't checked this make sure u do (this is where i've seen the most problems occur) see my post above.
