My system is wired exactly as yours is (unless I made a mistake somewhere), as I installed the control system from a C223 Trooper and connected it to my 4JB1's plugs.

It behaves exactly as you describe yours. I have not had the time to dig into this at all, but it is close to the top of my list now. The good news is that I have started the engine in some really nasty weather without the benefit of glow plugs (much colder than it ever gets in your part of the country, I am sure) and feel confident in the direct injection's design as being a good one for cold weather.

At any rate, in other threads (my conversion thread may have covered it, too) Jerry Lemond has listed some of the reasons the glow system will act like this. One reason is lack of power to the relays, if I recall correctly. This was the first thing I was going to check, as I did my own wiring and may have a bad connection. There were some other causes as well.

Failing that, it may be worthwhile to see if we could trick the controller into thinking it's got 6V plugs attached (if this is the cause of the trouble). If it's coming over the sensing resistor line, maybe adding resistance to this signal line would give the controller the reading it's looking for. This is just conjecture at this point, but it may work... unless I am picturing the system's function incorrectly.
