A crank sensor goes by a different name in this motor. I had hooked up a 12v test light clamp to the positive terminal of the battery and touched it to the negative side of the ignition coil. I then had a friend try to start the truck. I believe the bulb on the test light should blink to represent a switching signal to the coil. However, it did not. This leads me to believe that the pickup coil( aka crank sensor) inside the distributor is bad. The reason I believe it is this rather than the ICM, is because when it does start, it idles and runs fine. The ICM, correct me if I'm wrong, should cause the vehicle to miss if it was bad.
