I have a 1988 Camaro with a 305 tbi and only one injector is shooting fuel. i switched the injector wiring around and the problem followed the wire. so its not the injector. what should i do to fix this problem?

You can trace the wires back to look for a break or somthing.I had this issue with mine and a terminal at the ecm for injector pulse signal had opened and causing an injector to cut out.I pulled the terminal out and closed it some.Problem solved after that.No problems ever since.
