This may be a dead thread, but it's the best spot, I think. I have probably posted too much on another thread, but thought this might get missed otherwise, and might be useful to someone searching "pulse module" as I was.


With basically the same symptoms, I tried a used known good pulse module and got no fire out to the starter solenoid. I traced wires and had no fire from the clutch interlock to the PCM. I temporarily spliced into the wire from the clutch interlock at the pulse module, and got fire to the PCM, and to the starter. Apparently the PCM must "give permission" before the pulse module will do its thing.


Mine was an odd failure; possible rodent damage but no evidence found. I cut the wire from clutch interlock to PCM out and spliced in a new wire, and that problem is resolved.


If you are having problems related to starting, study the FSM and ask questions. Folks here can and will help.
