A little background:
I have two dead cylinders - #3 and #4. Ignition to all 4 has been verified, both with a strobe on individual plug wires and by laying the connected plugs on the valve cover and cranking it over. So my first suspicion was the trigger points. I removed the distributor to the bench and ran a continuity check across both contacts while spinning the rotor. I'm getting good make/break at about 180 deg dwell on each contact. I have yet to pull the injectors w/rail and test the spray in cups. If that looks good I'll check the compression next.

Anyway, I connected an analog volt meter to each injector lead and it shows a constant 12vdc from the moment I turn the ignition on. It continues to show voltage while cranking the starter, I tried leaving the ignition switch ON (not cranking the starter) for a good 30 seconds to see if something would "time out", kind of like the thermal time switch, and stop energizing the injector, but it never did. I did NOT try cranking the starter for a long period of time but maybe I should have.

So my question:
I expected to see a pulsing signal to each injector when I cranked the engine over, rather a constant signal. Is there something in the D-jet logic that feeds a constant signal to the injectors for a period of time when starting a cold engine?
