Reason I ask is that a month or so ago it was doing this flickering and one day
after I parked and turned the key off, I noticed that the pump was running ??
After investigating I found that the pump relay contacts had burned out and the
relay was not always disengaging when powered down. Replaced the relay and
no more flickering for a couple of weeks. Now it has started happening again.

So I'm wondering if the flickering light correlates with the pump relay getting a
"flickering" control signal ??

My injection initiates at around 14% IDC which is only just above my highway
cruising speed. If I get a bit of head wind or reach a slight rise the system will
be hovering on the verge of spraying. Logs show flowmeter counts of 1 or 2 for
a few seconds sometimes before I either accelerate of back off the throttle.

Could pump pulsation at very low injection rates cause the flickering light ??
