injector problem
I have a 1994 Chevy 1/2 ton 1/2 of the injectors are working 1/2 are not there is continuity between where the wires for the injectors hook into the computer and where they plug into the injectors. But no power to the injector, any ideas??? does the truck have a bad computer??
yes I checked fuses and relays. no breaks in the wires. all connections are clean.
Thanks for your time and help

The power to the injectors is supplied by a switched ign source. The ecm provides the ground path to pulse the injectors. Make sure you have power to both injectors key on engine off with a test light.. If so, hook your test light to the wires of the suspect injector and crank it. The light should pulse......
