My glow plug led stays lit for almost 3 minutes when its col, below 25 or 30. I think the timing is of gp's are controlled by an ambient temp switch,( someone correct me if I got that wrong) , so the colder the outdoor temp the longer the gp's are energized.

Yes

Your plugs could have failed one by one slowly now you might only have one -three left

also i havent tried plugging in yet...it has been unseasonably warm the last couple days. im going to try tonight.
thanks...
I just repaired a truck with a bad gpr
in a heated shop would not start unless it was plugged in
started like a champ when the relay was replaced but since yours is new that should not be the problem, check it with an amp meter make sure you are drawing 150-200amps when the relay is on.
