WTS light question

Hi everyone, been a while!

Got a quick question here,

In my '91 E250 Club Wagon, every now and then, the glow plugs don't work, acts like it's got a couple burnt out plugs. Dead cold engine, get in, turn key, WTS light comes on for 2 seconds, and goes out.

I haven't checked anything yet, cause i'm only home on weekends and don't have all the time I use to, but what can it be?

It can't really be a bad glow plug or 2 right? If it was a bad plug it wouldn't come back to life. It only does this every now and then, otherwise the light comes on for 10-12 seconds, and the van fires up by a turn of the starter!


Any ideas? Grounds? if so witch one?

Check all connections.
The new style controller works off of resistance feedback.

Mine would do that. It would short cycle some and sometimes work perfect. Started getting progressively worse. When I dug into it I found a loose post on the GP controller. When I went to take the wire off to replace the controller this happened.

Sorry for taking so long to reply, I seem to have fixed the problem.

I took off the controller from the engine, everything looked fine, connections and all, but I did a rusty nut under the relay, where it makes contact to the box, I cleaned it up, played with all the wires, been working great since.
