I am getting a pulse signal to the injectors, but its very dim on the noid light. I have verified it to be weak on the ground side circuit, and I have verified pins 101-106 are grounded solid. I dunno where to go next?
Its a 1981 280zxt . I did a cont test,a load test and they both came up good, but still weak ground on injector harness side.pins 101-106 inside the ecu are connected so I know its not an injector to ecu issue because they all do it.
nothing else is affected in the car, but the poor ground wont allow the 12v to the injectors. The power side is great, its only the ground side. I have even installed redundant grounds because the Z cars are know to have problems.
