Hello, With the engine cranking, can you tell if there is an injector pulse? Maybe there is no rpm signal?
Check the coil primary circuits, smaller wires, pink wire and white wire, with the key on, no crank, are they hot, use a testlite. With the engine cranking, the white wire should have a pulse on it. If it is hot, but, no pulse, I might suspect the pick-up coil or ignition module.
