Below is what I would check first,
1. check the below wires 2. Disconnect the crank sensor and check for power and ground to the sensor on the White/Black and Gray/Red wires. 3. Check the connections at the ignition module for being clean and tight. 4. Verify that the Pink wire at pin P is 12 volts key on and cranking. Verify the ground on pin K Black/White wire, on the ignition module.
Yes I remember that but I was not following the description you gave above? About the ECM case showed power? Or ground?
My info was actually wrong on the ground being pin K at the module this module grounds through the bracket, below another test and the diagram you asked for.
Next, probe the Blue/White trace wire at pin "G". As the engine is turned over by hand, the voltage should toggle high and low as the vanes pass in and out of the crank sensor. Do the same test on pin "H", seeing if it toggles voltage also. If either signal is missing, check the wiring to the crank sensor.
DId you ever do the test I described above?
Can you tell me in what order you installed all the new parts? Also do you know if there is pulse at the injectors?
