I have a 87 4Runner with the 22r Turbo. I recently have tried to get this thing running and I have fuel to the rail but there is no signal going to the injectors.. When I tried cleaning the ground cable to the wiring harness for the fuel injectors, I did try touching it to ground with the ignition on and got a spark. But when the engine turns over there is no signal. Is there a pickup somewhere other than in the Dist. or is it possible that its my ECU?
