Alright, well it finally got cold here and now that the glow plugs have to do their job they are taking at least 10 seconds at 40-45 degrees to cycle.

Is their a way to find out which ones exactly are bad and making the cycle so long? From what I've been told they should take 3 seconds at the longest and that's at colder ambient temps than I am at right now.
 
LB7/LLY take a lot longer than 3 seconds. you will have a code if you have a bad one. LBZ/LMM take a lot less time as there is a grid heater.
 
LLY= 11 seconds below 46* 10 seconds below 68* and 9 seconds below 90* of coolant temp.
