Used the LED"s on the DME harness. Not getting any signal from the speed sensor. Un-plugged at the harness, and had signal there. Used a jumper wire from sensor to DME plug and all worked well. I have a broken wire in the harness, so I will be changing out the harness.

Ok update time. Changed the harness out, and guess what, The exact same problem!!! I tested the harness before I put it in, by using ohm meter to make sure I didn't have any broken wires a crank position sensor plugs. Installed in car, same crapping thing!! I did notice however, the speed sensor led blinks when I quit cranking. Wanted to make sure it was not a fluke, so I plugged my NOID lite into the injector harness, and it also blinked when I quit cranking. I'm beggining to think I have a ground somewhere some how cancel the speed sensor signal when cranking. Any suggestions??

Sensor gaps rarely need adjustment, but the wiring at sensor connectors into the DME harness probably has issues. I can make my car stall on command wiggling wiring into these connectors. [I need to work on DME wiring this winter]. No fuel pressure - start looking for other wiring issues - you will need wiring diagrams to be systematic.
