Mitsubishi Repair: 90 montero v-6, crank angle sensor, wave signals

Question
I don't think I am getting power to the dist. on a working system i read a little over 5 volts on the red lead at the 4 lead on base of dist. checked the 3 main fuses and 3 fuseable links per linda. All seems good. don't know where to look for relays or if they are in that circut but i don't show any power at that link. I do have 12 volts with key on at the coil.

Answer
You should be getting a 5V square wave at both the red and black wires at the base of the distributor. The others (white) is the 12V supply and (green) is ground.  That you have 5V at the red one means you likely have a good power and ground. The real question is: Do you have, when the engine is cranking, 5V square wave signals from the red and black. If you only have 5V that never drops to 0, when cranking, you have either a bad TDC sensor (red wire) or Crank Angle sensor (black wire). The power from the MPI relay is what powers the circuit (white wire) if that isn't there, another quick check would be to check an injector, as they use the same MPI relay source.

A regular voltometer will not see the change directly, but will average the values at the engine is cranking over. It doesn't give you enough information as to whether the ground is going low enough to trigger the PCM (which then tells the ignitor) to fire the coil. A scope is best used here.  Don't use a test light on the black or red wires!
